didnt show any nameplate in pvp

Currently, these seems to be a general WoW problem, not related to Threat Plates: https://us.forums.blizzard.com/en/wow/t/enemy-player-nameplates-not-showing/1579528/13

Once possible fix seems to be to update nameplate max distance with

/run SetCVar(“nameplatePlayerMaxDistance”, 60)

or

/run SetCVar(“nameplateMaxDistance”, 60)

It does not seem to work in all cases though.

it works now as i typed i
/run SetCVar("nameplatePlayerMaxDistance", 60)
