I saw a quirk while requesting:
christine00
Marigold (Tagetes erecta 'Spun Gold')
I clicked on the Treasure Chest, didn't look closely at the next screen, but then saw the Treasure Chest had not turned to a green check-mark. Hmm.
Without thinking, I clicked th Treasure Chest again, and it told me that I already called dibs on that item. OK, I must just not have refreshed.
But F5 did nothing! I tried CTRL-F5, and it did reload, but I still saw only the Treasure Chest, no green check.
I was curious, so i clicked again ... and this time it gave me the seeds, AND turned the check-mark green.
Since I don't remember for sure the very first step that went awry, this is not a very good bug report, and since it clearly did the right thing eventually, it's probably not a bug at all.
But the refresh behavior at first was wonky.
And the green check mark did not do what I expected, or at least it behaved differently depending on which iteration I was trying.
The overall behavior was as if my first attempt to call dibs MIGHT have detected that I requested it yesterday, but it DID have a Treasure chest at that time. The next few attempts were strange, but once it let me request the seeds TODAY, it did know that I had dibbsed it today, and turned the Chest to a green check right away (without any refresh).
