[Raidobw2]

Describe the bug

For some players they seem to be getting a startup crash with a no class def error on the StoneBlock 3 modpack

Steps to reproduce

1. Install FTB StoneBlock 3
2. Start the pack
3. Crashes

Expected behaviour

That it would not crash on startup

Screenshots

I don't have any, but I have logs, most of which are found in https://github.com/FTBTeam/FTB-Modpack-Issues/issues/1597. Here's the recap:
