i've been experiencing something that i at least think is a bug or at least if isn't is rather hard to tell isn't a bug- sometimes randomly i believe possible triggered after a battle something that i think is auto battle happens? what i mean by that is after that point i'll get an aliment that looks like the paralysis or stun one but never goes away and forces all battles to go into a "autobattle" thing(i only call it that since it just randomly doing whatever the hell it wants and i haven't used the actual auto battle option so i don't know if it is exactly auto battle or if its something else) where i physically can't do anything no options at all. if this isn't a bug i would love for at least a hint as to how to get rid of it- only way i've been able too is reloading a previous save before i got it and as you could probable tell thats not exactly easy to do without losing a lot of progress...
It sounds like your bloodlust meter is too high. Any other states that take control away like that will wear off after a battle, if not within that battle. But the bloodlust ones will linger until you reduce that gauge. The easiest way is simply bathing or using cleansing water which the standard item shop at the camp sells.
Do let me know if that DOESN'T fix it though as then it's definitely a bug of some kind that I'll have to look into.
