'MYUSER` should be admin and allowed to build/remove blocks?
If I dump MYUSER I get this:
> permissions dump MYUSER 13:37:29 [INFO] [==== Page 1 of 3 ====] 13:37:29 [INFO] Node lwc.admin=true (PermissionsBukkit) .... MOAR ....
As you all see MYUSER has the
lwc.admin=true, and it's enabled in the admin group.
