Thanks a lot for your reply!
Was it maybe the heavy rain? It's more intense than the regular rain (try to change the weather by typing weather rain 1 into console, is this type of rain still too intense?)
I will test the 'weather rain 1' command. Will this setting stay effective until server restart or permanently?
I also like to know if there's a option to specify the abandoned sheds spawn rate or amount. Its beginning to look like there was a apocalypse and loads of people abandoned there sheds 
Or should I open another thread for this?
