So I'm using a script to speed up searches in Mupen64, it compiled fine when I first ran it and it has worked without problems for the past month or so, but today when I searched Mupen I noticed it was taking a ridiculously long time.
When I checked the script editor, it said: "ERROR: Preprocessor failed. Compilation is still possible if no macros or includes are used."
I'll restart my PC later to check if this is just a problem with RAM.
