Sometimes i am right next to a beacon (alone or not, doesn´t matter) and it doesn´t count as capture for me. Once in a while i get there, have the blue “capture-beam” and all of the sudden it disappears with no reason.
I cannot reproduce this, since i have no idea why this happens.
(posted this in rankings since, well, it´s the forums that gets the closest, since it affects rankings)
Beacon capture distance ist set to 700m radius around a beacon. Also there is a short time out of maybe 10 seconds, if you get hit or out of range, you will not be awarded for your effort.
Might have a look on it with this infos and report it back.
