This just began happening about a day and a half ago and is occurring in all my worlds: When I manually polish a building in a city, I receive the "This building has already been polished" message and the aid button goes dark; however, if I reload the screen, the aid button is lit up again. Manually aiding works fine as well as hitting the aid button - it's just the manual polish that is affected. I find this frustrating as I have Dynamic Towers and manually aid some of my friends/guildmates to gain goods of specific ages. I submitted a CS ticket and received a "We're looking into it" response. One of my guildmates has been experiencing the same issue - he posted to ask if anyone in the guild was having this issue and the only other response was someone who uses the aid buttons in Town Hall. Checking in here to see if anyone else is having this issue.
