I love cartographer as map mod. I replaced metamap with cartographer because it has a ace-like modern UI and awesome instance-maps. On some maps there are boss locations with loots when you left click on the skull.
But practically this doesn't always work, no matter how often I click on the skull. It seems that it is random (or pure luck) when the loot-list comes up. The only way to handle this is first to change location on the map and then switch back to the current instance.
Earlier versions (doesn't notice this in the current cartographer build) had the bug that in instances the skulls sometimes vanish when you open the map. I don't know if this bug is fixed in the current build of cartographer.
But this bugs are minor and you still have the best map-mod out there :)
Same here. It seems that for some reason, the modules deactivate themselves, although the "enabled" is still ticked. If you disable and reanable the instance modules (loot, map, notes) they show up again normally. If you close cartographer and re-open it though, the problem will come up again.
