Fresh install of the dev branch is throwing python exceptions anytime I attempt to launch a map. Tried spawning in as Harappans in 3000 BC and ended up on a map that was definitely not the DoC map with 1 turn research and build times, plus more error codes than I could count. Similar happened when spawning as China on 600 AD. Trying to spawn as any post-start civ causes a CTD.
Potentially relevant: I'm running the GoG version on Linux. I've had more or less perfect stability with Civ4, including the 1.17 release of DoC, up to this point.
Edit:
1. Noticed that all the vanilla map types appear in the play menu, not just DoC. I haven't tried launching any of them but I don't remember those being in 1.17 so it's possible that's indicative of whatever issue I'm facing.
2. Grabbed a screenshot, this is from attempting a 3000 BC start as Egypt
