EnderIO: Found the following problem(s) with your installation:
* An unknown AE2 API is installed (rv3 from appliedenergistics2-rv3-beta-6.jar).
Ender IO was build against API version rv2 and may or may not work with a newer version.
This may have caused the error. Try reproducing the crash WITHOUT this/these mod(s) before reporting it.

I forgot to check if Baubles is installed, as these items require it.

java.lang.NoClassDefFoundError: baubles/api/IBauble

Lemme push a hotfix within the next day. Otherwise (There's a lack of downsides) just install Baubles for the time being, it's a small mod and allows extra gear slots. (Belts, Rings and Amulets)

https://mods.curse.com/mc-mods/minecraft/227083-baubles/2224857

yeah that was the problem

Thanks for the confirmation.
I'll mark this as fixed and it'll roll out in the next release. Be it another pre-release or not.

https://github.com/draknyte1/GTplusplus/releases/tag/1.4.8.2-Pre

Baubles and Server-Side classes both fixes in this release.
