The only way this could happen is either myself of Putrefy changing it via RCON, or via a vote..
I’ve been away for the last week so wasn’t me lol
Are you sure it wasn’t a vote, ie: nextmap instead of endmap? as that would do the same and just change without warning if so.
Either way it sucks and shouldn’t be happening, nothing more frustrating that playing well and not seeing it through to the end.
