Description:
Attempting to update DynamicSurroundings serverside to the latest version yields this crash. Reverting to the previous version fixes the problem.

Can you post a link to your log file?

EDIT: Second question - which previous version did you have? Reason is that there were two BETAs prior and then of course the release version before that.

@korlandril I was wondering if you made any progress or had further information. :)

This would be good to know to as I also have Galacticraft running on a server, but have not updated to the most recent version of Dynamic Surroundings.

Closing due to inactivity. If you feel this is in error feel free to open again with additional details. @DWX12 The upcoming 3.6.0.0 release will use the Sponge Mixin framework instead of the traditional ASM approach for modifying Java code. It should improve compatibility a great deal.
