You must have a mobile/object somewhere in the mud to mstat, mset, etc...
In that you tried to mstat it and it said they aren't here.
You tried to mset it and it said nothing like that in all the realms.
Mlist shows it is there because mlist shows mobile index information.
Minvoke invokes mobiles using the mobile index information.
Anytime you try to mstat/mset something and it says it isn't there you probably will have to minvoke it so you can see and modify it.
