CTF indeed doesn't work on TSF with Carrotade, though, for whatever it's worth, you should be able to play regular Team Battle with no problems. It's something that somehow went unnoticed during beta-testing, and I would've uploaded a fix for it a while ago had I not started working on the merged 1.23+/Carrotade project.

Testing the same exact thing on 1.23 and then TSF gets so boring after a while...
