Well, that's annoying, the 4th one broke pretty early on today and started dragging. I pulled the whole motor and mount off, shifted the battery over so the center of gravity was away from the missing wheel, and then ran it on 3 motors, which it did surprisingly well. It's "straight line" paths were diagonally front-left and rear-right, but it wasn't that difficult to adjust to mentally.
Originally I'd planned on bringing in the parts to fix it correctly, but we've reconsidered as that'd mean 30 min or so that it couldn't be on display while we tried to fix it, so we'll just run it on 3 wheels tomorrow too.
Here's a clip of it running on only 3 wheels...
