You need to at least explain what you changed.

say what??

you need to explain slowly, and carefully what you mean, what you changed etc.

When I delete patrols, for example

Always remember to include all the relevent information for an accurate solution to your problem.

Also, you should know, that most mods don't actually change the INI files, they simply include a script file that tells the game to alter the INI files in a certain way. That is how the mods are able to be turned on and off. If you changed the INI files manually, It would be quite difficult to know where you went wrong. You may have to undo all your changes and try again. Or make an actual mod, meaning write a script file. That is alot easier to do than tracking down errors in the INI file. If you write a script file and it is wrong, the FLMM won't load it and you know it is wrong. It beats crashes that don't tell you whats wrong. Errors in script files are alot easier to troubleshoot because people here at TLR are quite familiar with them. There are also alot of tutorials on script files here in the forums.

Sanic

For example

[zone
nickname = Zone_Rh04_path_hessians3_1
pos = -35477, 0, 65745
rotate = -90, 75, 0
shape = CYLINDER
size = 750, 33223
sort = 99
toughness = 12
density = 3
repop_time = 90
max_battle_size = 4
pop_type = attack_patrol
relief_time = 30
path_label = hessians3, 1, 5
usage = patrol
mission_eligible = True
faction_weight = fc_rh_grp, 10
density_restriction = 1, patroller
density_restriction = 1, police_patroller
density_restriction = 1, pirate_patroller
density_restriction = 4, lawfuls
density_restriction = 4, unlawfuls
encounter = patrolp_assault, 12, 0.290000
faction = fc_rh_grp, 1.000000

So you've just been ripping zones out of your systems? I'd suggest you reinstall SDK. You also may want to go into the other thread where you gave a suggestion to someone else to do the same thing and let them know it causes crashes.

Thanks
