Hi, i suspect you updated your Forge, right? If so, check you Llibrary-1.7.17-1.12.2.jar coremod (it may cause trouble if outdated) Also, check your OptiFine_1.12.2_HD_U_E3 to be new version. I had same problem, and probably found sollution. Registered here just to tell you, if it's still relevant )
