For 1, 2, & 3.... thank you 
I guess I can live with #4 then for that 'medium run' then.

Hmm... the pnb plugin is causing trouble after the latest update, but I don't think these issues are really related to that. Can you reproduce the problem?
Well, it's when you stand on them to get pushed up to then mass-spam them into place that it starts going all wonky. You see planks deforming, logs rotating in fixed positions, and it just desyncs so quickly on servers that it's quite noticable. You may want to try replicating building a cabin wall + roofing yet make it about 64 logs wide, or something. Something around a block's worth to then try and cover the 'roofing' until you see planks spazzing out.
I'm sure I can replicate this, yet I'd rather not. It'll happen either way.

When I spawn into a server I tend to 'float' up into the air before dropping back down. Seems like we're a bit high before we join the server.
