Whenever I try to make a Pattern in the Pattern Terminal, it completely crashes my game.

Here is the log:

Please put your crash report on pastebin and replace the pasted crash report with the URL (you can edit your post BTW).

Can you reproduce this crash without Optifine and/or Minions?

I will try it without Optioned or minions

Still Crashes.

Here's the new Log:

do not post the crash log from withing the logfile, thre is a dedicated folder "crash reports" that contains the full crashlog .. you can attach it as file when commenting or use "gist" to paste large logs becasue pastebin has a pretty small limit

That log is incomplete. Most of the stack trace is missing.

I had switched over to the Rv3 Beta, still has the same issue.

delete the "1.7.10" folder inside your "mods" folder, you have probably a codechicken lib roaming there .... maybe you are missing it i can not read that from the log itself clearly ... it will download the needed lib-mods by itself again ... if it fails with the exact same error, you may need to download codechicken core ... but nothing so far i can see that is in any way related to AE

Seems to be working now. Thank you!
