The day of the latest update, after playing for some time I noticed an alert on the Apparel button on the main menu. I clicked on that, and there indeed was a new Apparel Cache to open. Opened it and accepted the Textiles in lieu of a duplicate item. Escape to close that window, and the main menu indicates a new item alert on the Apparel button. Clicked on the button, but there is no new cache to open, and there are no new item alerts on any of the Apparel categories, but the Apparel tab does show a new item alert.
Restarted the game, no change. Restarted PC, logged on TD2, no change.
Quit the game, enabled the Verify Files option from Ubisoft Connect.
When completed, logged back on TD2. There is still a new item alert indicated on the Apparel button, but in the Apparel menu there is nothing in the Store, no new Cache, and all apparel tiles (Cap, Glasses, Neck, etc.) do not indicate any new item alerts.
I selected each tile (Cap, Glasses, Neck, etc. and in turn selected each item listed on each. There are no new items found under any of those tiles.
