Just telling me things are crashing is meaningless without logs

"Ah, and fix the speed boost " You're gonna have to be a lot more specific than that.

which "speed boost" are you referring to

and which version are you using?

There should be no problem with that. I was just using it fine a few minutes ago.

I just tried it again myself, even recorded it. I am not seeing what you are describing at all. Edit: video here: https://vimeo.com/208369919

If I can't reproduce it, I can't fix it.

What mods do you have installed?

Interesting. That's a long list and will be time consuming to replicate. Do you have Industrialcraft installed? And are you using anything like Optifine?

wait, I do see optifine. That might be the cause of the crash for the lux capaicitor. I'll have to try it out later.
