I can't seem to get any of the starting resources to spawn for any of the teams when I try to use RSO with .16's pvp. I don't know if I'm just doing something wrong, but the rest of the map seems to be generating resources fine so I'm wondering if this is a bug.

PvP scenario is not compatibile with RSO. And since I don't have easy way to run it in multiplayer I can't test it much. From what I recall it would require pretty significant changes since PvP scenario is using multiple surfaces.

Fair enough. A workaround I'm currently planning on using is to generate the map and initial spawns with RSO disabled, then immediately save the game and renable it for the rest of the game. That way the vanilla resources will be there and (hopefully) RSO will happily Gen the rest of the resources further out.
