Ok so you're using forge 1.8.8? What kind of model of computer or desktop are you using, and os? I think the client side mod hasn't been updated in a while.
I'll ask our Development team if they have time or manpower to look into it - since they're a small development team, their main focus is on keeping the website, badges, simulator and minecraft servers working - the client side mod is kind of an extra-if-they-have-time-project.
