Made a slight detour on my way home last night to capture a portal and the links didn't drop... some of them were killed from the other end so are now dead, but some are still there.
The game wouldn't let me link out from the portal as it would cross existing links (which should have collapsed when I took down the portal.)
Portal is here: http://www.ingress.com/intel?ll=52.262066,-0.880418&z=15&pll=52.264742,-0.883302
Would be great if +NIA Ops
could concentrate on fixing bugs in the game rather than swinging the ban-hammer.
