So, test map. I made red and blue spawn points, and they worked fine; I didn't add doors and such yet but Red and Blue spawned in ther respective places and could change class without dying. Then I went and started working through the VDC Payload tutorial, and it was many, many steps before I got to a point where I felt I could try and run the level again. As far as I know nothing about the spawn points was changed, but now Blue always spawns in Red's spot (Red spawns in Red's own spot just fine). I've rechecked the spawn entities so if there's an obvious fix, it eludes me.
