So I'm using mod director to download optifine from their site, but I've noticed an incompatibility with this mod. In order to get optifine to run on first load you need to do some fancy thing. Here is the wiki page on it https://github.com/Janrupf/mod-director/wiki/Complicated-Mods

This mod seems to break that somehow, not sure how so here is the log which I'm sure will explain things much better:

If you need more info let me know.

I'll investigate, weird issue
