Ah. I am actually surprised there aren't more of those popping up. Those are all defined at MediaWiki:Common.js/TroopInfo.js. It was created to catch people introducing errors into the stats without anyone noticing. The problem is it's a bit of a pain to update the JS when the stats really do change.
One solution is just to disable the module. The other is to remove the flag from your personal JS so the module stops checking for you.
At one point I believe I began creating a Lua version of all that but I never got very far. The source data would have been kept on a regular article page, which would have made for much easier editing. Would be a good project for a decent Lua coder.
