Forum:Already upgraded wall, quest doesn't finish

So, I was upgrading the military office, knew the wall would be next, and used the second build option to start it. It finished before the office, and when the office finished, that quest completed, and I expected the wall quest to do so. But, instead, it keeps saying "upgrade wall to level 12" and if I click on it, it goes to the level 12 wall and says it can't upgrade to level 13 until the school is. Part of the game knows the wall is level 12, but others don't. I tried to find the 'help' section I read about in-game, but cannot. So, if anyone knows how to fix the issue, or contact actual technical support for the game, I'd appreciate it.
