Campaign Is Messed up!!

I was going through Fools Gold, and I saw a random level 4 Mortar in a weird place, It was really close to the wall, Almost inside of it... Supercell, can you fix this? We cant get the gold with level 1 troops for us lower levels, Thanks!:heart::heart:

Just went to check it and it seems like you are right, there is a bugged mortar on this particular Goblin Map. (Image with the base).
If we look at the walls near the mortar they show it occupies 2 and not 3 squares.
