• Java HotSpot(TM) 64-Bit Server VM, version 1.8.0_51
• Forge 11.15.1.2318 on 1.8.9
• OptiFine L5

Possible Solutions:

• Update OptiFine from L5 to M5

Recommendations:

• Update Essential from 1.3.2.4 to 1.3.2.7
• Update Skytils from 1.9.8 to 1.10.0-pre9

The same thing has been happening to me. I tried updating optifine, essential, and Skytils, but the same thing still happens

do you have any idea why?

my game crashed when i clicked skytils box so does it mean i have to delete it

or it can stay in mods folder till the fixing update?
