Crashing on Game Load

Hey all, just got Satisfactory re-installed with my mods, and I'm crashing while trying to load a new game. The game works and loads in fine with all mods disabled, so I figure it's one of them causing it. But before I go through the process of enabling/disabling my nearly 300 mods, I'd thought I'd ask and see if anyone had any ideas, first. It's not unusual for me to run so many mods, and this amount worked before I had to re-install everything.

Solution:

For anyone else who comes across this issue, it was the Challenging Milestones Mod from Andre.

seems like one of the mods has an invalid research tree and SML is failing to register it properly as a result this will expedite the disabling/enabling process: >debugmods

Follow this flowchart to troubleshoot issues caused by mods (crashes, unexpected behavior, etc.). More information can be found on the docs: https://docs.ficsit.app/satisfactory-modding/latest/faq.html#_how_can_i_troubleshoot_crash_issues

Thanks, Robb. I'm gonna employ that method as I do for Skyrim/Fallout. Just thought I'd see if anyone had any thoughts, first. I shall get busy tomorrow!

Robb•3w ago

Yup. By asking here you've got it narrowed down to "probably a mod that adds a research tree"

Aleanni ChalaiaOP•3w ago

That's completely fair. It's a process we must all go through

Robb, this mod has only some json files for contentlib. Do you what in them can be causing this crash? https://i.imgur.com/VFCHVXt.png

it looks like you skipped the json schema validation step. for this file at least https://docs.ficsit.app/contentlib/latest/Tutorials/Setup.html ah, you didn't have the correct schema line mentioned at the top, but once you swap it there are only a couple warnings can you cause the crash on your side as well? the only thing that immediately looks off is the fact that you have lots of fields mentioned that you have no intention of modifying (ex. you have InventorySlotsToGive 0, better to just exclude the field)

AndreAquila•2w ago

They are all automatically generated jsons with the multipliers, that i did at the time.
Will fix those warnings asap. But I couldn't reproduce the crash here.
