Description

When I change mod file's name, even just a ASCLL letter, it get crashed when chunks generating.
Actually it's not only happend on some particular mods, but for reference, log's above.
btw there's one detail, tc's crash is after world created a little time, but exutil's was at world creating progress.

EndlessIDs uses the filenames to detect what mods are present for mixins, which are used to inject code into other mods to make them compatible with EndlessIDs.
This cannot be done through the regular forge APIs, because forge is not yet loaded fully at that point.

Solution: Do not rename mod files

fine.

Wait, how about puting it into config file as an optional item? So modpack makers can rename mod's filename as they wish.
Sorry for the request but it's really kind of meaningful to some non-English country's users.

I figured out a solution that doesn't require filenames. It's a bit complicated but i think i can upload the fix later this week.
