Hey,

Whenever I enter a PvP instance I receive the following error:

Message: Interface\AddOns\MagicMarker\Config.lua:1065: attempt to concatenate local 'diffname' (a nil value)

I hotpatched the addon by adding the following to line 1064 of Config.lua:

and (type ~= "pvp")

This seems to fix the issue for me and hasn't had any other noticeable impact on the functionality of the addon.

This happens to me in BCC sporadically when entering pve instances.

2021-06-20 version (not .2 but I assume it will be present there as well)

Happens sporadically on re-entering an instance.

I got this particular error on zoning into Blood Furnace Heroic as a ghost.

Opened a pull request to fix this here
