We have a couple of keeps I know of that after a Keep take we can't claim them.
Castle Black Boot owned by the guild The Founders, This guild was the owner when the keep was owned by EP and DC and when AD took control of the Keep we can't claim it either, we get the message its claim by another guild.
Same with Castle Bloodmayne, no guild has been able to claim it for the past 2+ months, It's been owned by The Zamrock Legion for over 2 months,
Can we get them reset or something?
