At least a few months ago; I'm not sure of the specifics, but I don't think it was after adding any particular bit of hardware.

So far I'm at pass 5 and have run for 13.5h with no errors. I'll keep folks updated after the full week has passed.

I understand that's quite a while in tech, but I want to be sure. -- Cheers, Luna Celeste
