Individual authors should check their own maps, of course.
I'm sure you understand that it's nearly impossible for MX staff to play through the 98000+ tracks on TM.MX before updating them. Even if we tried, it would take years to accomplish.
If you (or anyone) find a map that doesn't work anymore, let us know. We'll check it, hide it if necessary, and PM the author to let them know their map needs to be updated properly.

After today's update, editor invalidates every map open in it.
Yeah, this bug is terrible. I hope Nadeo fixes it quick.
