You're welcome, and thank you! First donation from the forum, very exciting

Agreed, BitPay is a quality operation.
I submitted a support ticket with Avalon and let them know that BitPay already made the change on their end. The ticket hasn't been picked up or anything, but I'm willing to stay patient until early May. I also PM'ed Yifu to no effect, but again I'll give him some breathing room while the Avalon team scrambles to get batch 2 out.
Post back here if and when Avalon updates your address, and I'll do the same!
