Fleet Date/Time removed HELP!!!!

explaination

So here's the story, I run a rather large active 400 member FED Fleet. Been doing so for past year and a half, we have had our share of mutiny and useless eaters over that span of time. But always my team of Fleet Admirals and myself have used the Fleet Roster to weed out the good from the bad. From time to time we will do a purge of In-active fleet members who have not been online in 3 months or longer and have not donated anything to Starbase Construction projects. To make way for new members and not clog up the roster list. But recently I have noticed that the Date/Time has been removed when you hover your mouse icon over their name (in the roster) that would tell you when last time that person was online or not. Is this affecting anyone else's fleet? To me this is a HUGE issue. How in the world am I suppose to keep track of in-active Fleet Members in a 400 member Fleet? How am I suppose to tell if my Fleet Admirals are logging online to do their duties? How in the world am I going to keep track of my HUGE Fleet I have been running now???

Does anyone have any suggestions on the course of action I should take? Or any ways to go around this problem and find out the Time/Date of people logging online to STO?
