So from what i've stumbled upon is that Chaos/Immobile doesn't seem to be fully working when you cause it to a unit who has already used their action for the round into the next round.

Ex: Susano'o itachi chaos a unit after they perform their standard attack in round 1, so therefore its a 2 round chaos and wont go away naturally until round 4. Same thing applies to a 1 round Immobile sometimes.

But the problem is that it sometimes just goes away before it should, take the Susano'o Itachi example or even Shisui, I've fought people where the chaos comes off 1 round earlier than its supposed to and it wasn't cleansed with a heal or immunity/debuff cleansing. I've noticed this problem extremely frequently in Madara (Konoha Founder), and seems to be persistent in Arena. A friend of mine has also experienced this with his shisui. Now I don't know if this is considered a bug or if it has to do with control. Let me know below and if you've come across this. If this isn't a bug, then i'll repost into General Discussion.
