Original issue with all relevant information - SpongePowered/SpongeForge#2331

Any update on a fix for this issue?

Hey Tencao, sorry for the delay on this one.

I assumed that the crash was due to Sponge changing the name of an internal method Farseek was using (as described in the linked Sponge issue), but I can't find any record in the Sponge source of that name actually changing. In fact, I was unable to reproduce the crash using the version of Sponge you were using. I tried adding Biomes'O'Plenty since it shows up in your stacktrace - still no crash.

Could you try again with only SpongeForge and Farseek/Streams/Repose and maybe BOP, and tell me if it still crashes? If not, we'll have to work to isolate the mod that triggers this.

I'll try again later today and report back any findings

While looking into this issue myself, I found that this is most likely a duplicate of Ordinastie/MalisisCore#151
Adding MalisisCore to the list of mods mentioned above causes this issue to appear.

Thanks @Rautherdir for the update! I tested and confirmed that the crash only happens when MalisisCore is present. I'll close this issue; if the MalisisCore devs fix the issue on their end and then Farseek still crashes with their new version we'll re-open this.
