Something odd in requests...
According to the feed, 7 people had responded to my request but the construction count is 4/7.
I haven't requested anything else for days and closing game etc had no effect.
No wonder it takes so long to build sometimes.
The count vs feed has always been way off, not representative of credited parts but it's always been off the opposite direction---only a fraction of gifts appear in the feed "A friend responded to your request".
