version 0.5.0.248f

wanted to move some chests (from your chest mod :p)

2 chests didn't connect after placing
and the ones on top are super wierd: you can see the boundingbox on my cursor, but the visuals go the other way (reconnect wont help)

this is a single player world

So, the first issue (chests not placing back) is partially by design: notice that Charset's chests do not always automatically connect to each other - particularly when shift-clicking. Use any wrench-like item to connect them together (or to disconnect existing chests!).

However, it would be nice if sneak-placing a chest onto another chest would cause a connection, just like sneak-placing a chest item. I'll add that as a new feature.

The second issue is stranger. Does it persist after world reload? If yes, could you enable config/charset/module/lib.cfg's expert.enableDebugInfo option and, with F3, hover on all involved chests?

sadly i destroyed the chest and replaced it, i'll try to reproduce it next time i play!

I fixed some of those issues for 0.5.3. Not sure if all of them, but it is possible.
