I went ahead and updated my Forestry to the latest version again in hopes it would generate crash reports you could use.

Apparently the player got the following npe in JEI when trying to view Binnie's mods cranberries. However you can see the top mod indicated is forestry.

Does removing optifine fix the problem?

oh, I didn't realize the player added optifine to my pack. I don't support optifine.

I've closed it on my end because I don't support optifine. If you also don't support optifine feel free to close it there too.

This should be fixed by #2431
