I've tried fussing with all the settings but ever since the patch last Tuesday I still get normal alert popups and sounds, but no TomTom waypoints are added. I didn't change any settings and all addons are updated through Curseforge.

I've browsed through all the settings for both addons and don't see anything obvious that I'm missing. Let me know if you have any ideas, thanks! I can never get to the Undermine bosses before they are dead now because it takes me 15 seconds to figure out which direction to go :)

In the Silver Dragon Waypoints settings, it looks like:

X Automatically

X Mobs
X Loot

O While dead
O Use built-in
X Use MapPinEnhanced (this is checked but grayed out and I can't uncheck it - maybe that's the problem?)
X Use TomTom
O Use DeadlyBossMods
X Replace waypoints

Duration 130
X Remove when target popup closed

The MapPinEnhanced one being greyed out should just mean that you don't have that addon installed so that setting will be ignored.

To narrow this down, could you turn on the "use built-in" setting and tell me whether that makes normal Blizzard waypoints for you? (If it works, that means it's a problem with how I'm talking to TomTom. If it doesn't, it probably means it's something internal with how I'm deciding whether I should set a waypoint in the first place.)

I tried toggling every setting in that waypoints menu on and off and now all of my waypoint arrows are back. Nothing different in the settings from what I posted earlier - so maybe my config just got corrupted and toggling all the settings cleaned it up? Sorry for the incorrect post, I figured it was just blizzard breaking stuff during the patch last week but after a week figured I would ask.

Thanks for the quick response and the work on the addon, it's very nice :)
