I completed O1S for a weekly clear on Monday, 21 Aug, just after midnite CDT. I was eligible for rewards and got my page for this 21 Aug clear.
The reset for weekly rewards was 3 AM CDT on Tues, 22 Aug -- over 24 hours after my weekly clear.
I did not clear, nor even enter the duty, again until Sat, 26 Aug, around 18:00 CDT. I was in a 2-chest clear party of folks who had not yet gotten their clear for the week. Upon completion, only one chest spawned, I was not able to roll, and I did not receive my page for the week. Again, this clear was the first time I had even entered the duty since my 21 Aug clear prior to the weekly reset. Furthermore, no similar issue locked me out of o2s loot for the week.
I cannot imagine a problem more amenable to in-game investigative support. All that would be required to address the issue would be a GMs investigation of my clear times and the chat log around the time of the 26 Aug clear where I was notified that I was locked out of loot for the week, despite not having so much as even entered the duty since the reset.
Nevertheless, I am being required to waste tremendous amounts of time issuing a "bug report" over an irreproducible issue. It is beginning to feel like the support desk has an explicit policy of making it so difficult to have issues resolved that most players will simply give up and take their losses to avoid the prospect of having to deal with such a cumbersome and frustrating experience.
