Weird BUG...

Tis has been mentioned before but i thought it was a one off case:
Trade Goods - it says that as soon as someone builds a trade good (e.g. Frictionless Clothes or whatever) no other race is allowed to build it...but in the game i am playing now the Yor has already built 2 types of goods that were previosly built by me. I thought this was a simple error but when i talked to them the option of giving them the goods they (and I built) was gone...I think this is because the AI fails to swap the production when my colony builds that one per game trade good first.
