Kerbal Space Program

Using Windows-64, latest updates, stock game, all DLC.

When using the new alarm feature to track maneuvers, some of the vessels in the alarm list will show a frozen, static time which never changes. This happens to seemingly random vessels at seemingly random times, but they stay frozen once it happens. But...

Going back to the tracking station and clicking the offending vessel in the list will update the alarm time and get it ticking again. If you're too late, clicking the vessel will make the alarm go off instantly, only to realize you're at +4m on your important rendezvous burn. But the alarm won't go off while the timer is frozen.

My temporary fix is to go to the tracking station and simply click through every vessel to update the alarm list once in a while just in case.
