Map Crashes in MP, not SP

Here's a new one. My map was working fine in MP before. I made a few changes, republished, when I tested it on a server my game would crash every time the map finished loading (it would say click to join and then boom, crash to desktop). I tested it in training mode, no issues. Any ideas?

Tried that multiple times. It's a client crash.

we mappers have noticed quite a lot of times when we re publish a map , the meta data file does not always over wright the file . so causing a server side problem/client side problem .
dont know if its steam to aapg sync issue or a part of the searing publish issue but it does happen , so its always best to delete the meta file before any re publish just to rule out the publish error.
done this so many times i have now lost count lol.
to fix is to find in your pc all .upk files and delete them , then verify game cache through steam library game and it will re download all new ones.
