So i have an ironman save right now where i've defeated the fortress and got all the way to the end.. while this was happening i decided to take my science ship and explore the system.. which was apparently a mistake because now when i try to finish the chain with any of the science options it keeps telling me i have no science ship in orbit.. i can just send in a fleet and do that part just fine but i can't get either of the two science ends to come together, any ideas?
