Updating IC2 should fix this ;)

I am running the latest version of all mods

Yeh that’s true - soz about that. The maven from which I take the jars for development doesn’t specify whether they are ‘releases’ or ‘betas’, but as far as I can tell all more recent builds are stable and many bugs fixes and additions have been made along the way ;)

The crash report you posted claims IC2 is their version 109, while the most current release is 164. In fairness, the most recent version of IC2 marked as a 'release' is 109, while everything subsequent (so far) is 'beta'. You'll have to embrace the beta.

i try to shy away from beta build as many mods have left a bad taste in my mouth due to beta builds actually breaking the modpacks i have worked on lolz
