Describe the bug

Reproduction steps:

Open the linked swf
Click one of the saves and start the game

The game freezes here, after trying to open a savefile. Also, it crashes after a while with "stack overflow exceeded", after I moved my mouse for a while. I didn't capture a stack trace

Expected behavior

Expected: The game starts up fine, like in flash

I haven't figured it out yet, and the SWF might have some strong obfuscation, as FFDEC hangs when trying to disassemble it. The only observation so far is that nothing is visible presumably because the child is masked by the root movie, which makes it not render. But I don't know if the difference from FP concerns masking behavior, or maybe that in FP the root movie doesn't become a mask in the first place.

That's strange, we are using jpexs/ffdec routinely to modify the swf. (only the gui version of jpexs though) Maybe JPEXS 14.4 would work better as more recent versions have routine regressions in AS2 behavior
