Display MoreI'm having the following issue all of a sudden with my modded instance. I was using Fastcraft before, but this error is the first time it appeared when launching my instance.
Forge 10.13.1.1222
MC 1.7.10
Custom modpack
Java 7
Fastcraft 1.9
EDIT: tested it on a new blank instance in MultiMCv5, with forge .1222 and fastcraft 1.9 only, it starts without a problem... What's my issue then?
I've found the conflicting mod, it was GLSL shaders mod version 2.3.28. Disabling it the instances launches normally. Is this resolvable by any means?
