The problem is as simple as it gets. Vanilla plugin-less (same thing with plugins) SourceMod breaks the way music is played when one of two pre-escape finale tanks is in play. It should play "taank.wav" in this case, but it only does so for a split-second and then abruptly switches to "tank.wav", which should only play when a tank comes around during a campaign run.
Would be glad to hear anything helpful on this, am very annoyed by this ridiculous bug messing with the music.
