Can't trade techs

[Keeper_GFA]

Anyone know of a reason that techs would move from the "Won't trade" column to the "Can't trade" column. This happened in my last game, Jonas Endain wouldn't trade me any of his techs (that's fine we didn't like each other). He declared war on me and the techs moved to the "Willing to trade" column (as they always do when war is declared). Then when I went to finally make peace with him, his techs were all in the "Can't trade" column. The techs were still the same as they were back when they were trade-able.
I do play with tech brokering off, but that can't be the issue here (unless it is broken) as the techs in question were initially trade-able and I know for sure at least one of them he discovered for himself.

I guess he is willing to consider trading techs as part of a peace treaty, but when the war in over you have nothing remotely good enough to consider worth giving you his techs in order to get.


This does get annoying.

That's not it. It's not that he was unwilling to trade techs anymore. It was impossible for him to trade techs with me. Even going to war again didn't enable the techs to be traded.

One of the Undercouncil resolutions (Develop Secret Codes) blocks tech trading with non-council members.

Or, you were the only two remaining factions.

That's probably it. Although they may have been the only council members left at the time the techs became untradeable.

No, there were 3 others still around. And being the last two should only make the AI not want to trade, not unable to trade.
