Attack of the B-Team control issue!

[RetroSquirrel]

I'm not sure if I am posting this in the right area, sorry. I am in a hurry and I am new to the forums. Anyway, for some reason, I set my inventory key to B, however, even though it shows  no other thing is using B as a control, it still doesnt do anything when i press it. Any help? xD

B is the key for the Galactic Map (which is kind of more of a solar system map, but that name sounds cooler) in Galacticraft.  You'll need to unset that in the keybindings for galacticraft core as well, then it'll work.
