I'm getting this super weird crash ever since updating. I've downgraded to 1.4.7 and don't have this crash anymore. I'm using CreativeCore v1.7.3 for both. Here's the report:

It's caused by BetterFoliage mod. I will try to fix it tomorrow. There were no issues with v2.1.3 if you want to fix it temporarily.

Oh ok, thank you! I'll downgrade Better Foliage instead then.

I just wanted to note, on the off chance you weren't aware, this also affects the 1.10.2 version.

This crash still occurs with 1.4.11 for 1.10.2:

I downgraded Better Foliage to 2.1.3, this works, but it should not be the solution...

Yes i know, i will try to fix it this week.

It will be fixed in the upcoming update 1.4.12 later this week.

Fixed in v1.4.12.
