If you place two Glow Lichen like in screenshot, two of them will be destroyed.
I think that it can be caused by merging two of this Glow Lichens - check screenshots.
Is it intentional? I don't think so.
May occur with vines, I haven't checked.
How to reproduce the bug:
1. Place any block you like.
2. Place Glow Lichen on this block and on the ground.
3. Destroy any of this Glow Lichens.
