Achievement and music bug

[ASOkanarie]

Hello, Good job with the new update.
I have also found a bug: Beating the Tsar tank unlocked the "A Few Loose Screws" achievement for me. :V

Also I would like to report that sometimes the music stops during a boss fight. The music stays silent until it "loops" and then I can hear it again. It seems to happen whenever there are too much explosions (And possibly machinegun fire) going on. This has also been happening before this update.

Thanks for the reports! I've added them to our list of what needs to be fixed
