Description:

This bug happens when both TofuCraft mod and AbyssalCraft are installed. Placing the Tofu Aggregator in that mod will directly lead to a server side crash, and it destroys the world unless there is a backup.
I already reported this to TofuCraft's author and he asks me to post the issue here.

Crash report:

Affected versions ("latest" is NOT a version):

• Minecraft: 1.12.2
• Forge: 14.23.5.2854
• AbyssalCraft: 1.10.2

Latest log file for when the issue was present:

Closed this a bit prematurely, as I should probably make some changes on my side to counter other mods potentially doing the same thing.
Also a duplicate of #442

This is on TofuCraft's end. They're not handling capabilities correctly.

Both of these methods should fallback to their super implementations if they don't encounter the capabilities they're looking for.
