Hello,
Yeah, i will not do it. It has been reported by other players.
I don't want to spend my personal time doing your QA's job.
I've spent enough time on this at this point, now removing the mods, verifying the cache, then installing the mods back in just so you will know to forwards this to your developers.
Maybe instead ask a QA member to test this simple thing on a vanilla client that was installed without any mods to begin with, since that is what you are working on.
Start a game, go to a city, open "Task Manager" and repeatedly click "Trade" then exit that screen and enter it again and watch the RAM capacity that is being used rise until the game becomes unbearable to play.
