if you want optifine to work, too get forge version 2362

If you want to get optifine working, use forge version 2362.

I recommend you contact the developer, the forge devs cant really do much.

get forge version 2362, it works with optifine.

use forge version 2362 until optifine is fixed

So, i noticed that when i downloaded forge and optifine with the latest forge version, it crashes. I could've sworn i remember i got it working a few days ago, so i kept going through previous versions of forge and found it had something to do with 1.4.21.0.2363, and any forge version beyond that has the same error. The error in question The game crashed whilst initializing game Error: java.lang.AbstractMethodError

Our main culprit for waiting is most likely the fact that, MCP hasnt been updated to 1.12 as of this writing. This could also be the reason why optifine, which usually doesnt require forge, is not updated to 1.12 as well. So were basically waiting on Searge for this one, dont spam his twitter about it though.
