Great Wall Gatehouse not working properly

I know there is a place to report bugs in the game but first i wanted to ask if anyone else is having problems with the Great Wall Gatehouse.

On a previous patch i had a problem where enemy units could just walk trought the wall, locked or unlocked and with sotne walls on each side. I never had this problem again but i remember it clearly.

The problem i have in the actual patch is that sometimes the wall doesn’t attack, one time it was under attack while being built, another time it was destroyed while under construction (then completed later). In both cases the wall didn’t attack on its own nor by clicking enemy units.

Does anyone else had those bugs?
