AI asked for a trade. They had Colonial Engineering available and I tried to trade for it, but could not make a deal. Little later I researched the trade and when I traded with them again Colonial Engineering was not on their list and I made a deal with them offering that tech and they jumped on it. This is just one of frequent incidents where the list of available tech for trading does not appear to be reliable and true as to what is actually available. 

The faction involved was the Regul Corporation. This is a faction that is from the workshop and is well over a year old.

Has anyone else noticed anything like this? I don't think I am having hallucinations.
