Chisel: Errors like "[FML]: Unable to lookup ..." are NOT the cause of this crash. You can safely ignore these errors. And update forge while you're at it. EnderIO: Found the following problem(s) with your installation: * Optifine is installed. This is NOT supported. * The RF API that is being used (1.7.10R1.3.1 from ) differes from that that is reported as being loaded (1.7.10R1.0.13B2 from CoFHLib-[1.7.10]1.2.1-185.jar). It is a supported version, but that difference may lead to problems. * 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. Stencil buffer state: Function set: GL30, pool: forge, bits: 8 Forestry : Warning: You have mods that change the behavior of Minecraft, ForgeModLoader, and/or Minecraft Forge to your client: Optifine These may have caused this error, and may not be supported.
