Reported by Ersanio and spel werdz rite through the Staff Feedback form. This is caused by an internal fix related to map types and contexts which I never applied to the SMAS RAM Map, probably because I didn't notice it had contexts. It'll be fixed tonight.
#117: Broken contexts in the SMAS SRAM Map
Link
Thread Closed
This has now been fixed. As it turns out, the context data for the SM64 RAM Map, which is the only other map with contexts, was also left unconverted, so it seems like I simply forgot that contexts also needed to be changed.
