The answer lies within the message itself; '...due to RECENT events...'
I haven't the game files on me right now, but from screening the game code over the last few days I remember that the 'captured' flag is initially set to 5(?) and the 'end press' event (a.k.a. end day) has an option to decrease the counter by 1. I can't remember if it's a randomized function or happens every day, but basically it takes time to get rid of this 'flag' - might be that some other values or interactions can influence this process, but in the end it's a matter of time.
