It’s very unusual o see leaking axial caps as they’re usually better sealed.
Save this picture for all those wallies who chirp up on YooToob & various forums with the old 'axials don't leak' nonsense!

Final conclusion:
- 2 shorted pins on the MCU
- 4 traces eaten by axial cap
Thanks to all who pushed me in the right direction!!

Yeah, I did say better sealed. It doesn't mean that they never leak. Having said that I've not seen one do it in person, though I've seen large numbers of radials do so.
