On my rare hunting character after the icc patch, the routes and the marks disappeared from the world map (on minimap it's visible). On my other character they still visible (on both maps), and the options are the same. Tried to reinstall, wipe the datas etc, but still doesn't work.

I don't use that addon.

I'm experiencing the same issue, I use LeatrixMaps and am wondering if that could be what's causing the bug.

I had the same issue, but I noticed that those icons and routes were sometimes visible for half of the second when I opened the world map. So I supposed that there might be some issue with the frame strat level and some frames just overlap SD's icons/routes. So I went to AddOns\SilverDragon_Overlay\worldmap.lua and at line 141 I've changed self:UseFrameLevelType("PIN_FRAME_LEVEL_VIGNETTE") to
self:UseFrameLevelType("PIN_FRAME_LEVEL_WORLD_QUEST")
and at line 148
self:UseFrameLevelType(ns.CLASSIC and "PIN_FRAME_LEVEL_MAP_LINK" or "PIN_FRAME_LEVEL_EVENT_OVERLAY"); to self:UseFrameLevelType(ns.CLASSIC and "PIN_FRAME_LEVEL_WORLD_QUEST" or "PIN_FRAME_LEVEL_EVENT_OVERLAY");

Dunno if it's truly an appropriate frame-level type, but it fixed an issue for me.

Nice, it worked for me, thanks! :)

I had a feeling it had something to do with the strata but had no idea how to circumvent the issue. You're awesome, Keolwyn! Thanks!

Works perfectly. Opened file in notepad, ctrl+f for the old one and replaced with new one. Tysm! Hopefully the creator fixes it for the people that didn't know this thread exists! Been waiting for a fix and someone just told me there's a user fix here. TY!

thank you! I'v been scratching my head for hours try to figure out what happens to my icons, this fix it!

The weird part about this one is that it doesn't happen to me.

Alpha is going up which includes some changes to those frame levels.

I've seen someone elsewhere confirm that it was fixed for them, so I shall close this. Reopen if anyone is still seeing it, please!
