why whenever i copy a building and paste it back the tc and doorlocks are not mine.
Anyone know a fix for this ??

Have you tried "entityowner true"?

thats why im thick and your not :)

EDIT

/paste testbase entityowner true

does not give me tc or locks

entityowner changes OWNERSHIP, not AUTHORIZATION. for auth there is "auth true"

kk using auth true the tc is mine and so are the locks 
But the building when prodding it still comes under someone elses name 

doing /paste tomtest entityowner true - does not make the building mine
How can i become the new owner of this copy/paste building

As you can see from the pic below i have tc and am auth after pasting this back.
I did not make this building it just copied some ones base and then pasted it back using the command above
it is still marked as owned by another player.

this command does not work if i copy a building i do not own.

/copy tomhud
/paste tomhud auth true entityowner true - (it will always show the owner as the orginal owner)

• entityowner true/false - default : true - Copy entity ownership of building.

this is from my config 

"Paste Options": {
"Auth (true/false)": true,
"Deployables (true/false)": true,
"Inventories (true/false)": true,
"Vending Machines (true/false)": true,
"Stability (true/false)": true,
"EntityOwner (true/false)": true

I wished the entityowner was explained more because i assumed it passed the ownerid of the building to the person who was pasting it back.
Spent a lot of time messing with this only to fail
Seems entityowner will never give you the building - its added for a different reason.

It copies ownership from previous building and optionally pastes it the same way. If there was no owner for entity recorded, it is indeed set to the person pasting it, otherwise previous owner. It does not enforce you to be the owner.
