you have to install both the STBC 1.1 patch, foundation from BCUT and(for bridges) BPcoregold once all of them are installed to the BC root directory, run BC and goto configure, there should be a fifth button called mutators, enable extra ships and mods once you have installed your mods, then go back to the mutators menu and enable theyre mutators and then go into quickbattle, you should then see that you can now use the extra ships, bridges and functions, i hope this explains it, let us know if you need any more help k?
