Previously, my Cartographer would create a note on my map every single time I would speak to a flight master. It would make thing easier in case you have trouble finding one in a village. Unfortunately, one time it just stopped occurring, and no more notes would've been created. I haven't noted other issues with addons for Cartographer. I don't recall what the plugin was called, however I don't see any that would be named specific to that.
Has someone else had this issue and maybe has an explanation for it?
Maybe you were using FuBar_ToFu or InFlight? They place flightmaster icons on your map if you're using Cartographer. I'm not aware of a carto-specific module that does it.
Ahh, then that must've been it. I always thought it was Cartographer that was doing it, however I was using Fubar_ToFu previously. I believe I disabled it because I really want to try to hone down my memory usage, but at the same time I want to continue everything that I'm using.
