STACK LEVEL TOO DEEP?

XP doesn't always do it, it depends on the error. When is the error called up? What's the game attempting to do when the error comes up? It may mean you're missing a dependency for one of the scripts, and thus possibly missing an aliased function (so a function, somewhere, is actually referring to itself and thus calling itself repeatedly - I came across the same error writing up large parts of LSX's stuff before I started overwriting default code).

Is it coming up with the error when you actually start the game, or when you try to test a battle? Does it occur in both situations? Which four scripts are you using? It's possible that the standalone versions refer to some of the same functions and could, possibly, be interfering with one another - but if I know what scripts you're using, I can actually look at the scripts themselves to see where they might be causing the error.

Another question - what order are you putting them in in the script editor? That in itself could be causing the error if they're in the wrong order - I can't much help with what order they should be in... =/

I'll take a look through the scripts, but my initial run through says they should work as is.

Edit: By my thinking, it should be...
Core Engine
Equip Engine
Battle Engine
Battle Command

But that's just from my quick look through the scripts. Those last two I know for sure, I'm just not 100% sure where to put the Equip engine.

Anyways, I need to sleep, if you can't get it figured out by swapping orders around, I'll take a better look tomorrow/after I wake up. - T

Do you have any recursive functions? Because I know a great way to make the stack much smaller. Don't use recursive functions. Recursive functions are only very, very, very, very rarely better than looped functions.
