I got a report from a new player today he tried connecting to TSA_Thunder Rift on Funbocks, and got a "Map version differs from Server." Deleting it locally didn't help either, so it seems the autodownloader couldn't fix it. I sent him a version of my map, hoping that helps, no feedback yet.
Burner also just notified me that a few of ELH also got the same problem with Death Valley.
It's really strange, considering these are default maps.
