What I expected to happen:

I work for a server hosting company, and we have a preset template for FTB Infinity Evolved 1.7.10 - 2.6.0. One of our customers used it and brought an issue up as the server wouldnt start
What happened instead:
The server crashes while loading, printing a NoClassDefFound error (see attached) https://pastebin.com/HRhHbPJU

only this mod errors, we run java 1.8.0_181 and update regularly, on a linux OS dedicated machine.

try botania alone, perhaps another mod is messing with it. a fresh copy in case the jar got corrupted.
the 1.7.10 release isnt supported anymore, but it should be mostly stable and usable.
