@ aramil248 Sounds like its sheer luck that it works in base. The limit was not decreased in OpenJK nor was any of the code surrounding it altered. Are you by any chance using the x86_64 bit version or the 32 bit? If you are using a new enough build it should give more specific details of which function. (CM_FindPlane2 vs CM_FindPlane) As for OP, I assume you are using jamp on windows?
