Well i found a workaround
in server console i typed o.show group bvip
then i copied the text from the console window ( not the permissions but the group members )
added it to a text doc
then did that in all my servers and combined them into 1 txt doc
then replaced the start of the usernumbers ( first 6 numbers all the same 765711 ) from
765711 to o.usergroup add 76511 then added bvip ( with a space to be o.usergroup add 76511*********** bvip )
then copied the entire list and pasted it into each server and successfully updated all my servers to all have the same usergroup members.
> o.usergroup add 7656119*********** bvip
Player '7656119***********' added to group: bvip
>o.usergroup add 7656119*********** bvip
Player '7656119***********' added to group: bvip
> o.usergroup add 7656119*********** bvip
Player '7656119***********' added to group: bvip
So if anyone else needs to do it, that is a simple work around that i did.
no doubt theres easier ways hence this thread but with no replies or suggestions this is the best i could do lol
