I had a few simple mods installed, I removed them all (I removed everything from the Saints Row IV root and re downloaded / verified game cache through steam)
Still the same, mod works fine apart from the map. I tried both camera views , they both work fine. When I press tab I can access every option apart from the map, as soon as I select map the game bombs out / crashes right away.
Ill have a look around to see if anything might cause the map to crash.
