Game can't deal with playable character becoming Glut's spore servant

[Gaius]

So, I was trying to do Glut's quest to take over the Myconid colony and one of my characters was killed in the fight.

I ressurected the character with Glut's spores and then won the combat encounter. The reanimated character just left the party (even in the interface at the left).

After the fight, the quest completed, but just after the dialogue ended my characters entered combat with Glut.

I killed Glut, but my reanimated character didn't die (like other Glut's reanimated corpses) - it just stayed in enemy state. Other NPCs kept joining the fight and all my PCs died.

After that, the game didn't consider me dead - no game over screen, just stayed at the same place centered on my (spore servant) PC.

I think the game lacks some condition to either kill the character or at least give you a defeat screen, some trigger seems to be missing.

Sorry if this was confusing, English is not my first language.

Similar issue, but a bit different.
After Glut turned on me, he made my main character his spore servant. Oddly I still retained controll of my character though. I then defeat Glut, but my main character remained an enemy (in spore servant mode)
