The game crashed on launch with my modpack. The debug log was not created, but I've provided the latest.log. It looks like it may be an incompatibility with Sophisticated Backpacks Obfuscate.

Latest Log

This is actually a conflict with Obfuscate. It's odd that my mixin error handling stuff can't catch Redirect conflicts.

It can't catch Redirect conflicts and most other kinds of conflicts because they're considered a "critical injection failure" and don't notify error handlers. Grr..
