Since last night, Optifine and Rift Voxelmap won't work together anymore due to CustomColors error path

i've submitted the issue already on Optifine page: sp614x/optifine#2183 but could also be due to Rift.

This is very strange, I am getting this exact error as well since last night. So I guess something related to rift/optifine is connecting to a server which has now changed in some way or something?

Fixed in Chocohead/Rift@173f0df
