Not sure why but one of the gems here just doesn't want to render. So much so it crashes the game.

Bringing attention to this once again, testing after 2 weeks with a different mod set and still the same issue.

I suspect that the "Ender Dragon" gem is somehow causing other mods to act up since it has no texture or model applied. Ascended does not do any fancy rendering, and that is the only thing I could see causing any issues. Here is a datapack which removes the gem I suspect to be causing this issue. If further problems persist, report this to Apotheosis instead of this repository, I wasn't able to pinpoint the offending mod based on your crash reports, though "Exposure" is mentioned in both.
