1. Get into a party (We tested with 5 - 10 party size, crash occured eventually)
2. Have crewmates go into the turrets
3. Do a mission (We tested protect fuel/escort and general Merc spacefighting missions)
4. Quantum travel to mission location
5. Game may crash for turreteers, pilots dont seem to crash while entering quantum/exiting quantum / in the middle of a battle
6. This might be an issue with party sizes/ multicrew interaction/ similar feel to the sound bugs in previous patches wthat made multicrew impossible)

What happened
Conditions:
1) I was in a big party, with 10 members across 3 ships distributed.
2) We did a Escort ship/Protect fuel tanks orange contract
2) I was in a Polaris turret along with a second turreteer, the main guner and a Pilot, (4 crew members). Also happened in a Perseus
3) Location was Stanton and Nyx
4) Crashed ocurred when quantuming, or when exiting quantum, or in the middle of a battle and someone was in a turret.
5) Pilots seemed to bne unaffected by crashes
6) Crash occurs often, not always

What should have happened
The game should not crash when entering/exiting quantum, or when having party members participate in a mission.

Workaround
Have no one on the turrets while quantuming decreases the chances of a crash, but not always
