I've running into a weird problem.

I've done the main part of my new app in one mfa. (with nice graphics,...)

one frame with some technical needs i've done in an seperated mfa without nice graphics, just for testing as long till it works.
as the code works fine, i've copied it to the new app. strangly the frame crashes mmf2 if i jump to it by another frame.

BUT: It works if i set the frame to the same position (frame number) as in the 'trial and error' project i've copied the frame from.

this seems really strange to me and feels like a bug.
