I did something similar with FOMM-Fork. The first time around I kept getting error messages at the start of the game but everything seemed to show up in MCM. Then following GSDFan's advice on this forum (#27, second spoiler), I used FOMM to install several mod families (all the Project Nevadas, all the Advanced Recon) at one go before going back into MO to create a mod from the accumulation. The recommendation from GSDFan was to install, at the end, MCM, MCM Bugfix, oHUD, and FlashlightNV as a unit, but in that order. Then finally all the mods were enabled in MO at once, and I went back to FOMM for the Unified HUD install. When I tired to run the game the first time, no go. I had to put the Flashlight NV in the optional panel. Okay, fired up the game. Hooray, no error messages. But it seems some major mods I added after that will not allow the game to run. My install won't run with the New Bison Hotel mod, for instance, or Afterschool Special or Fierce Power Armor. I stopped trying after that. Meanwhile, all of these mods were working together in a former all NMM install. And by the way, Darnified fonts show up only in my opening menu. In the game, biggish fonts. In the MCM, biggish, somewhat blurred fonts. I have checked the fallout.ini. I have installed the Darnified menu in Project Nevada serveral times. But no. The MO install is just too temperamental. I feel this has been fun sorta, certainly educational, but in the end too iffy to go with. Meanwhile, great big thanks to EssArrBee (SRB?), whose S.T.E.P. page on FNV is terrific. And thank you GSDFan.
