If your character dies in mission you preview on mission editor and you use team switch you lose some sound effects, gun sounds from all units are lost, Character sounds like breathing & sounds from moving etc. are gone. (If you team switch before you have died, everything works fine.)
- Legacy ID
Create simple mission where you have multiple playable units and get killed with one of them. Then team switch to an other soldier and try firing, no gun sounds. (on your or any other units' gun) Atleast ingame radio communications still work, but I dont know if something else bugs aswell.
