Back to School not working properly

Tron told me that "Back to School" is buggy on 19.
I tested it on 21 and during loading of map 2 my client crashed.
Server was still running fine with map 2 loaded.

Maybe other custom campaigns have also problems now.
Maybe it is related to the last game update yesterday.

Found that:

Maybe the client fixes could help.
Will give it a try soon.

This time the server rebooted with Alarm Clock sometimes.
The client did not crash but the second map could not be loaded due to this Alarm Clock error.
It seems that this map sometimes takes too long to load.

Tested the campaign again on 16.
Only this campaign installed.
Removed all other addons.
We could play it without any server or client crash.
So maybe the campaign conflicts with some other campaign.

I've started alServ2016 again with just "Back to School" and 2 other campaigns.
So if you want to play "Back to School", you could try it on alServ2016.

Yep the map is buggy. I don't know why is this happening but if I play any other custom campaign my game doesn't crash, but after finishing 1 round today my game crashed all the time after each round was finished. Anyway I found a bug too where you will get spawned under the ground once you connect, but after I reconnected it didn't happen again.

Clients also crash in Back To School when you are using addons like improved blood textures or similar
