On my avatar picture (top right, UI not in a match) I noticed I had 3 ‘announcements’(? not sure what to call it). Clicked my avatar pic to check it and it was telling me I had received 3 crates (all different ones). clicked ok on each and when I went to the inventory I only had 1 crate.
Not sure if either the loot drop or the announcements(?) are broken or if it was leftover announcements(?) from the last test 2 weeks ago.
P.S. if it was leftovers then developers could consider making it it so that announcements(?) were synchronized with the inventory. As in: if item is no longer available in Inventory the corresponding announcement(?) would be gone, as not to confuse the user.
