Yes, remember these are only quick fixes until ckk gets back to it, if he ever does. Who knows.
Sadly, i've had to stop using it myself, as there is a major memory issue with it right now. It goes something like this:
When you're low level, just starting, there is no problem as it's not populating the maps with POIs in the unexplored areas for some reason. Trying it on a high level, where all the maps have been explored, it processes ALL the POIs and, guessing an update problem somewhere, it almost brings the game to a standstill. And that is with all other addons disabled.
Mine usually runs at around 1.1 Gb fully loaded. With Carto3, it pumps it right up to 1.8 Gb. I'm guessing it hits the limit there, and starts paging it to disk, with the resulting game-stopping lag it causes.
Would be nice if he does get back to it. I'm sure I can whip up a few decent modules for it... :p
