Spezielle Dachtexturen sind in Arbeit 
Was die Ecken angeht: Ich weiß welche du meinst, die werden ebenfalls noch hinzukommen.
Neue Blöcke über LUA einbauen ist aber leider erstmal nicht vorgesehen, LUA läuft wirklich rein serverseitig, und bestehenden Game Content erweitern bzw. in dieser Hinsicht sogar Kernelemente zu verändern bedarf schon richtiger Mods
Yes, it is possible that the current multiplayer issue prevents you from connecting.
But it is also possible that your firewall or antivirus program, @Degalbro, is blocking the connection. What antivirus program do you use? You can try to temporarily disable both, and then try connecting again.
Done, disabled for one higher layer
Wir werden der Sache mal auf den Grund gehen! Möglicherweise ist es ein Problem, dass die properties-Datei unter Windows angelegt wurde, und demnach auch Windows-Zeilenumbrüche enthält, die Linux fälschlicherweise mit in die Werte hineininterpretiert? 
Das ist offenbar nicht dein Fehler, sondern Fehler des Spiels. Wir suchen nach der Ursache
Thanks for the video! 
Everything seems to be fine there. Please let us know if there is a spot in your world which often has collision issues.
Achievements are planned as a low priority feature 
Most achievements also don't make much sense right now, since survival mode is not a real survival mode yet.
Unfortunately, we will not add more languages in the next time. Keeping them all up to date is a lot of work, especially since we are doing frequent changes in the game affecting the language files.
But we will add more languages (as many as possible) in the future, when the game has reached a "more finished" state
No, with wood planks as construction element I meant those thin planks, craftable at sawbench, which can be rotated and scaled and freely placed in the world You are talking about the blocks, aren't you?
The default port 4255 is already in use, either by another program, or by an instance of the game running in the background (by not correctly shutting it down)? Or do you also have a dedicated server running on the same computer?
But you only used wood blocks? Or also those real wood planks (as construction element)?
This is not a technical limitation, it's a decision on our side to keep things simple (several functions per event become really confusing when it comes to callbacks and results) and also getting better performance result^^
But using a global table sounds like a good approach!
LUA things will generally become easier as soon as our wiki is available
If I restart my game, then it is fine for a little bit, however, it will come back again eventually. Sometimes setting a 'mark' in that area, then walking off, and using the 'mark' to get back also makes me fall through the ground in that area.
Is it always the same location?
About the goto and mark commands: They we're not officially working yet, so they may cause you fall through the ground often. It is only strange when collision never loads for an area, i.e. returning to surface by using F2 and still falling through ground.
1. Planned
2. Naturally flowing water is a really hard task, especially traveling larger distances (like for rivers). I'd be glad when we have flowing water, or water at all in the game
3. Yes we can do that^^
4. Fire is coming soon, as well as firewood
But you placed it that way on purpose? Perhaps we will restrict object overlapping in the future.
If someone else has the same issue: Please report it here. The error indicates that communication with steam went wrong. It may be related to server issues with steam (which is happening sometimes, especially now during christmas time).
But if that error occurs frequently, this is definitely not normal.
my version is 0.5.1.1
0.5.1.1 is already the latest version
Thanks for the video! This is a different "falling through ground bug" than most others (which are mostly caused by pressing yourself through small tunnels, or because world generation is not fast enough).
I was hoping that this kind of bug you have was already fixed. Is collision always missing for this location? Or does reloading the world fixes the error? If it is always unplayable, please send me your world, that helps finding that issue (but only if collision is always missing at that location)!
If the error just occurs sometimes, at random locations, you can fix collision for that area by editing the border of the neighbour chunk (destroy or place a block and/or edit terrain).
You can also see when collision is missing by typing "collision" in the console (really only a debugging command).
can you give a ruff idea what is in the next update and when will it be?
First we will release a bugfix shortly, solving the multiplayer related issues. After that, we bring another update, containing new objects and perhaps (so no guarantee for that feature) tree replanting^^
Endless worlds are indeed not the most important feature at the moment^^ And before implementing endless worlds, we will first add different biomes and dungeons, to have some variety.
Currently the worldgeneration is somehow endless (the game only knows about your current location), as @Geneo and @Jackah already expected, but floating point precision errors cause the game to become more and more unplayable when walking too far away from the spawn (the playable area is big enough though).
So we will work on this feature when the time comes
