I'm playing a pack I put together earlier this week. Worked just fine at first. Today I started it up again and after loading through almost all it kicks me back to the minecraft launcher with this error:
Googling the "Error: java.lang.NullPointerException: Rendering overlay" suggests something with Optifine but I dont have it installed. I don't usually make my own packs so i have no clue how to work error logs or anything like it. Earlier today i was somehow able to fix it by disabling and then reenabling hwyla, hwyla harvestability and more overlays as these are overlay mods. This however doesn't work this time around.
Thanks in advance for any help and pointers.
