my savegame kept on crashing. I now found out, that it does that on a small Ufo crash into a tram. So I tried to deactivate Ufos by unticking the Ufo option in TTDX configurator 2.8.9. Unfortunately, this doesn't help, the Ufo is still there, searching for a tram to destroy the world

Can anyone help? I attached the savegame; the Ufo is right in the middle of the screen...
