Weird error when using a custom save script.

[DerVVulfman]

Well, if you deleted the MACL (or specifically one piece if you just downloaded segments... it's possible), you deleted one module that handled battle simulation. If you had a custom battlesystem that needs the MACL, you need the MACL... or at least a part thereof.

Below is the MACL Battle Simulator module at the very least

MACL - Battle Simulator

Code:
