Playing as Britonae. I have just taken the option to add a feast, which gives 5 loyalty for 12 turns. I already had this in play, it was running out that turn, so I thought I would set the next one going to replace it.
When I ran the turn the old one had finished as the 12 turns were up, but the new one which should have been on turn 1 of 12, was also cancelled.....
