Title states it all. I've attached my crash log (or rather, the link to my OneDrive, which has the crash log. My secret garden project is in there too; oh well...) to this thread. I think it's a 1.8 Optifine problem because 1.8.4 Optifine works fine for me; however, I need 1.8 Optifine to "merge" with Liteloader for one profile. https://onedrive.live.com/?cid=153EBA71AD3634BB&id=153EBA71AD3634BB!123
Try sending ShelLuser a PM, he seems to know a lot about Optifine. Other than that, does Optifine have a contact email? Might try asking them directly.
