I'm experiencing the same problem as Ppanda0421. Black screen on load-up with the UI visible but no cursor, movement, or right click menu.
IWBUMS 38.9 worked fine yesterday. I was building up a base in New Denver, the house on the coast with the corn plot.
Mods are New Denver map, Bedford falls map, Hydrocraft, driving cars, more zombie loot, Silencer/suppressor, Pump Power.
I can start a new game in New Denver with all the same mods and it works fine. I ran over to the coords and the map is loaded. Can anyone outline which files I would need to move over from original game file to try to recover world and character?
