When stacking signs on top of each other, and destroying the bottom one, only that drops as an item. The other signs just disappear.
Also, when a sign is placed on a wall, and the block it is on is destroyed, the sign doesn't drop. The same goes if the sign is on the ground and the ground block is destroyed.

It is also like the bug where destroying the block under a door doesn't drop the door, although it seems that that bug was FINALLY fixed with the last update 🙂
Same problem here 😞, THIS BUG was similar to The cactus in 0.3.0
