I'm having trouble with Solar's UFOs via YetMoreUFOTypes. Sometimes missions involving the fighter, sentry ship, excavator, and lab ship run just fine; and other times I get the "invalid vector<T> subscript" error (whatever that means, especially since I don't play nightlies) upon trying to start a mission with those UFO types. I have no idea what the cause could be, so I've resigned to just using Solar's UFOs as large scout variants instead of separate types (i.e., using YetMoreUFOs instead of YetMoreUFOTypes). I guess that also means no lab ship, unless it's a battleship or supply ship variant?
Speaking of supply ships, there's a weird supply ship map that looks like it's not finished. It's like half a ship, and obviously not an intentional design because it's missing UFO components like power sources. And y'know, there's a giant hole in it.
