As it used to be in dw20, @elbite and I are building in team, but now our claimed areas can't be attached one to each other. I mean, between my claim and albite's there are about 8 blocks not claimable ("You are too close to another claim"). How can we attach our claims to make a continuos claimed area like in Direwolf20? Thank you!
This was implemented to stop players being claimed near, what you could do is put all the claim blocks on one person and they claim the entire area instead of two different claims.
The best thing to do would be to have your friend do /abandonclaim then do /claimlist which will tell him how many claimblocks he has available, then do /sellclaimblocks <amount> to convert those claimblocks into myms, then do /pay <yourusername> <amount> to transfer those myms from him to you, and then finally you can do /buyclaimblocks <amount> to turn those myms back into claimblocks which you can then use to extend your claim to cover the full area
