I used 'pop' for two different scripts and the game crashed.

The first one was a single byte script, which was something like

dec esi

and should be changed to

inc esi

but using

pop esi

crashed the game.

Another example script looked like:

mov dword ptr[esi], -0.5f

which I replaced with

pop esi
mov dword ptr[esi], -0.5f

This also resulted in a crash.

Is this an intended behavior ? Tbh writing garbage in your game hacks also result in a crash :-).

If you need the exact script names let me know.

Intended behavior, you should always try to balance push/pop commands, as these effect the stack.

For every pop, there should be a push before it somewhere.

And the x86 isn't emulated in this game by design, so assembly bugs can easily crash yeah
