same here, did entire playthrough with no guides and never ran into something like this. Was just very thorough on each map, like any rpg I play.
Only complaint I have is the underwater prison in act 3, that one I save scummed. The game makes it seem like Gortash is gonna blow it up in a instant, but you have enough time to dock and do your thing. That is not clear at all, and if you try to go back a second time, then it is instant.
If it works with any git platform, you have several alternatives + self hosting.
The chokepoint is the index, but if the mod repo is up and you have the url by some other way, it should work
