Claim already summoned

When trying to summon a claim a second time I get "Claim already summoned".
Is this something new? Before I could summon claims unlimited amounts of times.
Does it have some timer when it resets so it can be summoned again?

Kind of sucks when some uber mob stands on the claim.

That has been so for more than two months, since 14.5.

This was, as Haruto said, changed quite a while back... Most likely to avoid people summoning multiple times to move claims out of lootable pvp, and such.

Remember, the entire point of claim summoning was NOT to let people move claim to a safe spot, but to avoid those situations where claims were unreachable (inside stuff, in steep cliffs, etc).

Ok, guess the situation havent occured for me latelly.
I won't whine about the change, it is just a question of adapting
