0.C-12184-g21b426f- Vehicle has disappeared

Basically, my armored truck/halftrack that I had worked so hard on disappeared. This isn’t just for this build, but for earlier ones like 0.C-4100 and upward. The last build in which it worked was 23a8629, or 0.C-3870.

I am also using the SDL version of the game (I can use tiles).
