Describe the crash or bug
Inputing orchard grain or crafting orchard bread in an ME system crashes the server

Steps to reproduce the behavior:
Try using orchard grain

Expected behavior
Getting orchard bread or having orchard wheat in the ME system

Crash log or latest.log.log
Not the server owner so unfortunately don't have the logs

Additional context
Did not test with other versions of the ancient seed products but i suspect they would do the same

Without a log I can't really do much. Also from looking at the description of what you wrote, this would more than likely need to be reported to the ae2 developers.
