Spam much? There is an edit button

One (or more) of your mods has an outdated CofH Energy API. Update everything that is using RF Power.

Ill try this with java 1.8 now

I can confirm this is an incompatibility issue with thermal expansion.

ok i had this issue without using redstone arsenal. I read something about the same problem.

And as soon as i add in computer craft and openccsensors it shows the same thing

openccsensors is the problem!

Redstone arsenal doesnt work too!

Thanks @grimallq - @EEVV, do what grimallq says, that should fix it.

Hello @unpairedbracket, you may be interested in micdoodle8/Galacticraft@7d8331b and micdoodle8/Galacticraft#791 - you're welcome to use anything from that commit if it is helpful to you.

nb. see also micdoodle8/Galacticraft@0a6972c (more try/catch statements needed for the RF API v2 presence checks to work correctly)
