I am missing the 375 Allagan Tomestones of Esoterics I accumulated from July 28th to August 3rd. I only signed on once for maybe 15-20 minutes the following week, so I'm not entirely sure when they disappeared, but I'm assuming it has something to do with the maintenance that was done on the night of Monday, August 3rd. I signed in to the game on Wednesday, August 12th and saw that all my Allagan Tomestones of Esoterics had been wiped clean. I know I had 375 because I was one Expert Roulette run short of capping for the week and mistakenly assumed the maintenance was supposed to happen at 11:00pm pst. I signed on not long before maintenance was actually scheduled (at 9pm pst) and, unfortunately, did not have enough time to do my Expert Roulette. Thank you for your time and any assistance.

Are you sure you aren't looking at the weekly cap breakdown? That resets on Tuesday's (for the US). There should be two listings, one is your actual X/2000 (hard cap) and the other is your weekly cap (x/450)--that second one is the one that resets weekly.

Yeah, I'm sure. I was at 0/450 as well as 0/2000. I saw it on the lodestone and signed in to double check. I've also capped for this week and am currently standing at 450/2000, which should be 825/2000 if my tomes hadn't disappeared. I haven't made any recent purchases with them, either.
