After the maniaplanet update thingy I can't seem to upload new replays on maps like https://tm.mania-exchange.com/tracks/99228/tmu-stadiumd1. I get the error "Replay uploaded mismatches the title used in the track (Replay: Unassigned, Track: Stadium)."

What do?

Thanks for the report!

It should work now wherever you encountered that error.

All Stadium maps that had no TitlePack were previously tagged as using the "Stadium" TitlePack.

I've converted all 5463 of those maps to "Unassigned" TitlePack.

Replays should now upload without problems.

You can find the maps by filtering for Unassigned TP:

Nice quick fix, thank you!
