I can confirm this exists in 1.03.
I have a row of pistons that extend across a chunk boundary. on occasions when the chunk is loaded, pistons in one of chunks will load as previously described. The problem can be cleared by destroying the wooden surface of the piston. The piston will then extend as expected.
so far, it has only happened in one of the chunks and not the other, it is usally all the pistons in the affected chunk that are in this state, but I have seen on one occasion that only some of the pistons are affected.
Running on android 6
I can confirm this issue. Pick, Sword, Stack of iron bars all lost during trading.
This happened in a Realms world
