Grabbed Victim: Not go to jumping state?

[STM1993]

maybe sending the grabbed opponent in some new frames where he falls and can't move...

I tried that, it doesn't work.

What I've done to test is to alter the picked_caught frames used in Dennis to have dyy: 550 and next: 201 so Dennis should freeze in mid-air and then turn to ice. I had my character grab Dennis while someone else attacks me.

While grabbing Dennis, Dennis remains in his picked_caught frame without going to next. That's okay.
When I dropped Dennis, Dennis goes into falling frames. That's okay.
If I get interrupted while holding Dennis, Dennis goes into jumping state immediately. This is not okay, I want him to turn to ice if he is no longer grabbed as a result of the grabber being interrupted.
