Some items missing from a mod not from Attack of the B-team

[Wildoneshelper]

I've downloaded Railcraft mod to Attack of the B-team and some items are missing. Coal coke is replaced by poppet from witchery and I could not find creosote oil from Railcraft mod as well in Attack of the B-team. Is there a way to let the vanished items appear again? Thanks!

Sounds like an ID conflict.

Just change the affected items' IDs in the config of Railcraft.

Fixed, thanks!
