I just tried to set a block withto a glass pane, that block had near another glass pane and a block.
The setted glass pane sticks to the other glass pane, but not to the block.
How can i solve this?
You will need to update the glass_pane by removing the block next to it and placing it again.
You can use commands to do this automatically and fast so that it's barely noticeable.
/setblock <x> <y> <z> air
and then set it back
