It's hard to tell, but some of the pins on the south side of the AVR look pretty close. But if it checks out with the continuity test, probably fine. Maybe double check the decoupling capacitors on the back of the AVR?

FWIW, I'm at 3 working out of 5 attempted builds. The very first one I attempted, I screwed up the AVR. At least when the AVR isn't functional, you can stop early. Then in the last batch I ruined the CPLD on one, removed it, replaced it with a new one, and AFAICT, it's all good except one CPLD pin is grounded that shouldn't be, and I have no idea where. That one is 100% assembled before finding the problem.

So, sorry about that. I can't really offer much advice, just empathy.
