My friend and I want to add Buildcraft and Portal Gun mod to Attack of the B-Team. It works fine on both of our clients, but when we add the mods to the server, it ends up crashing. Localhost doesn't even work for my friend. We downloaded the mods for our clients, and got the Buildcraft and Portal Gun server files from the Direwolf20 FTB pack. Anyone know what our problem is? If you need any info, feel free to ask.
