I found an issue with the number of turns left on the Ghost status not counting down correctly.
The defender had Claire with the Soul talismans equipped, I had the Corrupt General.
I killed Claire, triggering the Ghost status with 3 rounds left on it.
I was able to stun Claire while in Ghost status, but a turn as stunned Ghost did not decrease the effect lifetime.
I stunned her for three consecutive turns and after that she still had 3 turns left on her Ghost effect.
Only when I stopped stunning her, allowing her to act during her turn did the counter wirk normally again.
I verified this in battles against my own defense, ghosting some allies with Carriage Rider Eddie, this is reproducible:
stunned ghosts will remain ghosted as long as the stunn remains active, the turn counter does not decrease.
This did not work when CRE ghosted himself and was stunned though, it only worked on allies.
If a ghosted blocker is repeatedly stunned, the team it blocks for effectively remains unkillable since the ghosting is prolonged by this bug.
