So I beleive I have found the problem... Carbonite does a quick scan of every area for quest updates.. Pettracker has things it does everytime the map is updated which combined with the rapid map switching carbonite does, creates a small lag
I do set a variable when carbonite is about to do it's scan and unset it after which addons encountering this problem can check for, and in a quick test of adding it to pettracker it seems to be fixed
Can someone else who is having the problem try adding this to pettracker.lua on line 61 it should be right under
function Addon:WORLD_MAP_UPDATE()
Code:
if Nx and Nx.Quest and Nx.Quest.WorldUpdate then
return
end
