When using '/sm gen 2 8' the map isn't generated. The below is printed to the console:

ArgumentException: A null reference or invalid value was found [GDI+ status: InvalidParameter]

/sm and /sm map return the expected text in-game normally.

Can you post the full error that appears in console? It should have more information. I'm also going to assume you're on Linux?

That's correct. Thanks for the quick reply! Here you go:
