There are 1.7.10 versions now! Yay! They all seem to crash on my server! Boo! :)

I've tried 29-31 and they all crash while loading on the server, client loads without problem. Possible rendering issue? Similar to the #1 issue I opened back in September for 1.10.2?

Thanks a lot!!

@silent-mobious Do you have Mekanism installed? If so could you check that you have the latest version of Mekanism for 1.7.10? That has solved similar issues before.

No, I wasn't using Mekanism on the server at all. Nuclear Physics alone is crashing with the above error. I just downloaded and installed Mekanism-1.7.10-9.1.0.281 and it's crashing with the same errors:

Hopping in to mention that I've just run into the exact same error on my server with many mods. Error reads exactly the same. Everything worked fine when i tested in single player. Verified that server runs fine w/o Nuclear Physics(tested 30-31).

Super stoked you've picked this up btw. Can't wait to use it.

Thanks for reporting, i will investigste :-)

This bug is fixed in latest release. Thank you @silent-mobious and @cadaverific for reporting!

Grabbed 32 and it's confirmed working on the server now. Thanks a lot! Awesome mod!
