I am going to commit a small faux-pas and quote myself...
Yeah... a lot of heart ache and ill feelings could easily be handled by some kind of communication with all the groups currently having concerns:
Avalon B3 units without PSUs
Chip orders
FPGA Trade-ins
Refunds
That being said, I can understand refunds being at the bottom from a priority standpoint. I just don't understand from a complexity stand point. There is clearly stuff that we are not privy to as to why refunds are complicated and difficult. We just don't know it, so people assume the worst.
I think we have an explanation for why Yifu has been MIA:

Hopefully now that is over, we will see some updates.
