When I go to "My FlyerTalk" I see the following new subscribed thread:
but that post at 1:14pm (GMT-8) does not exist.
Probably it was deleted by the mods, or there is a glitch or something, but either way, (See below) it was moved into that thread from another thread, and since then that message has been "stuck" as a new post in my "New Subscribed Threads" since yesterday.
This is on the "FT Desktop" skin*
This may be related to the bug I've occasionally noticed where you reach, say, page 9 of 10, and you click on next page, and it brings you to page 9 again because there really is no page 10 (again it seems inferentially that a previous post which caused there to be a 10th page was subsequently removed)
(It's getting harder and harder to resist the temptation to make a throwaway post to the thread just to get this to go away -- OCD

)
*Interestingly, in the mobile skin, it says "New Subscribed Threads: (1)" but if I tap through to > Subscribed Threads > Subscriptions, that same thread does not appear. So it's counted for the (1) but does not actually show up in the list.
