Never Mind, this topic is a duplicate D:
It is weird how it comes now. Did they even change torches?
This is a very weird bug, I get it on all my devices with Minecraft PE. But I seem to have found a temporary fix.
What you do is: Break the block you want to put the torch on, then replace it, now try placing the torch.
Sadly, this only works when your trying to place it on a WALL at a corner and it moves to the other wall.
I get what your saying, being a mod and solving duplicates is hard. But people always make up different titles so the search function doesn't always work
