Muting and unmuting music causes weird music behaviour

Big Pharma Pharma Support
1
  1. Muted music for ~25 minutes to watch a TV episode.
  2. Unmuted music.
  3. If I change to tabs other than Production, the music no longer changes like it used to (e.g. becoming more “jungle-like” on the ingredients tab).
  4. If I return to the Production tab, the music mutes. To get it back, I have to either open the Options menu and Apply Changes (without making any changes), or wait for the song to cycle to the next one.
