Test 2: First SMU, Vault 111 finished with corpse audio log so mainquest works, exit Vault, quit game, install SimSet and Conq. Restart game, install+config popup, then nothing. No display in the top left corner after 15 minutes. Because I thought that was strange I checked my installed mods and HudFramework was disabled, probably the cause, not sure though. After enabling HudFramework and restarting the game still no display. Test 2 failed
Test 3: Start SMU and SimSet+Conq simultainously, with only two other mods active. You´re special (FO3 and NV option) and HudFramework. Again my go-to start via SMU (Ex-Gunner, near V111, level 1, essential gear). Enter V111, everything goes fine and everything works like it´s supposed to be. Exit Vault and stayed in the area, put my character in the vault lift controll booth and waited. Stage 1 complete after 1,5hrs. Stage 2 and 3 completed in maybe 20 minutes (didn´t really watch the clock here, went to the kitchen, took stuff for sandwich to my desk, made sandwich, ate it without a rush, took the stuff back to the kitchen, stage 3 done). Stage 4 again 1,5hrs. After completion I went to the first settlement that I knew was affected by Conqueror, the cinema thingy east of Drumlin Diner (always forget the name). Did not activate my other mods yet. On the way I passed by Abernathy Farm. And behold! Houses and ruins and fields and stuff. With people! Some woman talked about seeing a centaur and another ghoul dude said I´d be a synth cause I had not given him 50 caps.
I´d say Test 3 was a complete success. Have not tested it with my other mods yet, but since those are mostly weapons, armor and some settlement objects I don´t think it will break anything. My biggest concern was Start Me Up since that one is especially tricky. The scripts will break when there are too many scripts running along in the initial phase and when the scripts break that´s it. Main quest completely ruined, to the point that you can´t even fix it through console codes.
Seeing the mod work after hours upon hours of waiting and multiple tries to get everything right was surprisingly satisfying. I´m glad I didn´t ragequit after the first problems arose. I´ll do a quick test with all my other mods and then I can hopefully put the solved tag on this
