Spore Repeatedly Crashing in the Tribal Stage

If I load my save and try to play, the game will close itself after a certain amount of time. I thought saving more often would be a safe workaround, but the crash is like a time bomb where I saved with the timer at 00:25. Pausing the game also pauses how long until the crash, but I can't find what's causing it. My tribe is currently fishing and I heard that's known to cause crashes, but if I order my tribe to stop and move elsewhere, it won't make a difference. I have tried running the game in compatibility mode, as an admin, with a lower resolution, larger cache, and with a deleted GraphicsCache. I have not socialized with any creature before evolving, including my own species. The game does not crash on any other save.
