After cutting down a tree, if a block is placed on the block of land where the tree stood before it returns to grass and is then destroyed, the sound of the tree falling will be played.

I will try and see if i can reproduce it.

Same thing happens to me. The sound is played if a log is placed near where the tree once stood.

Also was randomly getting this error and kicked from the server when other's would chop logs.

(Internal Exception: java.lang.IndexOutOfBoundsException: readerIndex(31) + length(1) exceeds writerIndex(31): PooledUnsafeDirectByteBuf(ridx: 31, widx: 31, cap: 31)

happens to me too

Should be fixed in the latest version, if not then please open this issue again.
