Basically, we had arena_crossfire for Randomizer and TF:GO Arena, and the latter was selected for next map/gamemode.
However there was a buildbot update in the middle of it, refreshing mapvote's plugin and forgot next gamemode is TF:GO, picking Randomizer instead.
It should be possible to prevent this, but takes a bit to do so in such a rare situation, so low priority.
