Okay, so I did something to address the save you uploaded, but I couldn't verify if that actually dealt with the problem, because the relevant portions of the code have already been executed on the turn the message is displayed, which is why I asked for the previous turn.
(I will address this before/while doing the other thing I've mentioned because Congresses will not be affected, so don't let yourself be discouraged by the recent announcement from submitting saves.)
