If you can't fix this issue, then at least point me to what other mod is causing this.
Also, this only became a problem when I added Logistics Pipes to the pack, hence why I put this here.

Ok, this is odd.
Just started making a personal tech pack and the same thing happened.
Curious, I tried with only LP and BC. Still the same result.
I assume that there might be something wrong with my download or it is conflicting with my version of forge, 11.15.1.1808.
This is also all done through the Curse launcher, if that provides any help at all.

You are using Minecraft Forge for 1.8.9.
As far as I know Logistics is still for Minecraft 1.7.10.
So no this will not work ever.
Either wait for 1.8 releases of Logisitics Pipe and Buildcraft or downgrade your Modpack.

There is no LP version for MC 1.8.x yet
