Talk:Twin Vipers/@comment-69.224.218.18-20130624232136

Since this costs two vipers, that means you need two viper BPs, which I bought. However, it won't let me build both at the same time, so I have to wait for one viper to finish, then build the second viper, then finally build the twin vipers? Is there any way to build both vipers at the same time w/o rush build?
