Long time modder on other games just now trying to mod bg3 after finishing group play through with firends, and running into this same issue. At start-up the modsettings.lsx is re-written to contain ONLY the gustav mod settings. I followed the advice above and removed the mod fixer but something else is still re-writing that file, If I watch the folder and immediately replace it with the config with the other mods, it seems too late, the other mods never activate when creating the new game. (I've also deleted the cache files before starting) regardless On the initial load screen it either hangs at 93% or writes a new modsettingslsx which includes only the gustav.pak and nothing under the <node id="ModOrder">
