I noticed a bug while trying to acquire the Space Weapons technology from another player via trade.  If I offer them all my money (2,500 BC) in return for the Space Weapons technology, they will refuse it.  However, if I then ask for Mass Driver Theory technolgogy in ADDITION to space weapons, they will accept it for only 1,200 BC.  The same thing happens when I try it with Beam Weapons Theory instead of mass driver.  I'd imagine Missle Weapon Theory would also have the same problem.  I'm using TA 2.03.

(I ask for Space Weapons tech / I offer 2,900 BC) = Refused

(I ask for Space Weapons tech and Mass Driver Theory tech / I offer 1,200 BC) = Accepted

I wasn't able to find a previous post on this subject so I thought I'd share it.
