Got this error today when doing dungeons. Maybe related to the removal of the position stuff? I don't know, but would be nice if you could find a fix.

Thanks in advance!

in 7.1 "GetPlayerMapPosition" got remove while in instance (and in party too?), my workaround:

in file "ElvUI_Enhanced\modules\maps\minimaplocation.lua"

local function UpdateLocation(self, elapsed)
    location.elapsed = (location.elapsed or 0) + elapsed
    if location.elapsed < digits[E.private.general.minimap.locationdigits][1] then return end

    xMap.pos, yMap.pos = GetPlayerMapPosition('player')

    if xMap.pos then
       xMap.text:SetFormattedText(digits[E.private.general.minimap.locationdigits][2], xMap.pos * 100)
    else
       xMap.text:SetText("---")
    end

    if yMap.pos then
       yMap.text:SetFormattedText(digits[E.private.general.minimap.locationdigits][2], yMap.pos * 100)
    else
       yMap.text:SetText("---")
    end

    location.elapsed = 0
end

Seems to do the job!
Thanks!
