The more I think about it, the more I feel like the rule that would make the most sense is if Throne Room, King's Court, etc. just never stayed out. I mean, it's not like the Throne Room actually has any direct effect on the next turn. If you TR a Fishing Village, then yeah, you get two FV effects at the start of next turn, but that's all set up by the FV itself, not TR. I understand keeping it out for tracking purposes, but with the weird rules regarding TR and Outpost, Tactician, etc. I feel like it ends up being less confusing to just never leave them out, even if that means making tracking more difficult. Unfortunately, completely backtracking on a rule that's been printed in an official rulebook since the second expansion isn't very realistic, so I'm not sure what the best ruling would be at this point.
