Two minor issues in survival-
-Redstone torches that are off (e.g. alternating positions in a ladder) will behave as if they are on; when either this torch, or a properly “on” torch is connected to a redstone circuit and then removed, the circuit will remain stuck “on” until the redstone dust is removed and replaced.
-Leaf decay-- doesn’t appear to happen, at least within towny protected chunks (I haven’t tested outside town limits, but this does appear to be independent of attachment to solid blocks, i.e. they are not decaying when they definitely should)
edit1: It occurred to me that the leaf decay issue may exist because leaf blocks contained in chunks copy/pasted from 1.1 are considered “player-placed” and therefore won’t decay. I will test if leaf blocks from newly planted trees exhibit the same behavior.
edit2: Hypothesis disproved- leaf blocks from newly planted trees will not decay, at least within town limits.
