G'day again, seems you run both Reliquary here and sophisticated backpacks.
So, you might have also seen this issue: P3pp3rF1y/SophisticatedBackpacks#453

The same crash also makes mention of reliquary as another crashing source in both the latest log and crash report. Please take a look at them and let me know if these are user error or just something you stuffed up and need to get updated.

Same solution - you need different jvm to run forge modpacks.

yep. thanks. soon as they realized, they checked their java and updated it and it ran just fine.
