Problem with round changer in TTT server

Sorry guys, I’m new to Lua scripting.

So basically getting to the point, I need to stop the round changer. After every 6 rounds it stops the server and attempts to change the level, but every time it does that it just glitches the server. I’d basically just like to remove that from happening, I’m not sure where this is even programmed to do this. I can’t find it in server.cfg or anything like that. Here’s a picture to show you what I mean,

I can’t really see the problem in that photo, maybe I’m not trying hard enough.
To answer your question, overriding CheckForMapSwitch() should stop the round changer; untested though but…
A better approach than disabling map changes could be fixing the problems caused after a map change. Can you give us some more specifics?
