Happy to see you sorted it, well done
If it ain't broke, test it to Destruction.

My guess, a bit of both. The broken pin certainly wouldn't have helped, but the solder whisker on A16 was effectively jumpering both 1M and 256k at the same time, so not helping either.
Glad you're up and running, back to fixing up my Mega now
