Hmmm...I know if something like a grave stone is blocking a portal one can get an error saying "error, portal blocked!" but I have never gone through it. Is there a chance someone else close by to my base has created a portal and blocked it and its interfering with mine? I tried to go 300 or so blocks away to setup but error remains. Any ideas?
is the sign under 1 of the middle blocks ? that normally happens if its on the side of a portal xx x x x x x x <<not here xx ^sign here
