Infinite state change loop when fighting a character's AI.

I've been having trouble finding the issue in a character I downloaded. The character in question is a 1.0 conversion of Ken Amada & Koromaru from P4A, and the crash only occurs under some pretty specific conditions (but maybe it can happen in other cases as well). When I use a 1.0 conversion of Margaret from P4A, and I use her Ardha grab move on an AI Ken while Koromaru is out, the game gets an infinite state change loop error. The Ken does not have any custom AI from what I know. As for code, I'll just post the state in question that seems to cause the problem according to MUGEN.

It's a very big state with many different states that it can go to, so I've had a lot of trouble figuring out where to start. I can always post more code from other states, as well as Margaret's code if that helps too. Hopefully it won't be a very difficult error to fix, but I doubt it will be a major issue if a solution can't be found.

It says stuck in infinite loop in state 4000? Find a changestate that puts it into 4000. I can't see anything in that precise state thatll loop it.

Alright, there are quite a few changestates that go to 4000, so I'll just post the parts that are changestates so that there aren't a bunch of chunks of code. I'm also excluding changestates that are from special moves and such, since those most likely aren't the culprits as the AI isn't using those moves when it crashes. I'll also mention that this applies to a helper that's often active, so they work seperately from the actual character.

This is from the state that stops the helper's walk.
Code: 
[State 0, ChangeState]
type = ChangeState
trigger1 = AnimTime = 0
value = 4000

This is from the state that makes the helper get up after being hurt, though it's identical to the previous statechange.
Code: 
[State 0, ChangeState]
type = ChangeState
trigger1 = AnimTime = 0
value = 4000

This one's interesting, since I have no clue what it does. It's in the -2 states though, so maybe it's important since it's probably always active. It also tells us that the helper's ID is 300, so that can help.
Code: 
[State 4000, Koromaru]
type = Helper
trigger1 = !numhelper(300)
helpertype = normal
stateno = 4000
ID = 300
name = "Koromaru"
postype = p1
pos = -100,0

I figure I should give the code for Margaret's move that causes the crash as well, since what it does is probably important considering that other moves that grab Ken don't seem to have the same issue.

I figure State 4000 is the Helper's standing/idle state?
I'm not seeing anything in her state that should cause a loop.
You may just need to edit 
anim = ifelse(Root,StateNo=191&&Root,Time=0,99999,3500)
to
anim = 3500
and create a change anim to be

triggerall = time = 0
trigger1 = (Root,StateNo=191) && (Root,Time=0)
vlue = 99999

Yeah, State 4000 is the helper's idle state. I tried using what you suggested, but it unfortunately didn't work.

Did it make any difference?

Try adding,
triggerall = time%3 = 0 
to
[State 4000, Koromaru]
type = Helper
trigger1 = !numhelper(300)
helpertype = normal

I don't think that'll be it, but a slight possibility.
It could be in your hit reaction states. But if it's caught in a loop it's usually that state that's the cause.

One thing I could imagine is since P2 is attacking you, it could be the state P1 is in is conflicting with all of your changestates.
triggerall = ROOT, movetype != H
Add that to your changestates. Unless you can imagine a situation where you'd want that to happen??

Hey, it actually seems to work! Probably because that's the movetype of the grab. I'll just keep it and hope that it doesn't mess anything else up then. Thanks for the help!

Ok so if the Time % is what worked, it seems it could be an order issue.
I think if you reorder the states that should help it out also. Mugen goes down the list of states and reads what's active. Then if something deactivates it it gets deactivated. Then if there's a spawn that happens even lower, well there's your loop.

You might want to add IsHelper checks to some of your states also.
