locs
The scout locs have never been an issue for me at all. Is it all the locs that won't update or are you just having trouble with one of them?
I have never been lev'ed getting those upates, and size of the toon does not matter, like some of the other locs in SoD.
First update is straight out from zone to commonlands, its between the two houses on the road.
Second update is in the small walled camp southwest of the first update, also near the road. There are obliteration guys in it, but they won't agro.
Third update is near a house with a bunch of obliteration folks infront of it, further southwest from zone in. This one is the hardest to explain, since its not actually on or near the road, but due west of it. Where the road makes its last turn south, towards the house at the lake, head due west. The update is somewhere along that line between the bend in the road and the house out in the forest. I've gotten this update 4 or 5 different places.
If you're having problems with the updates, a trick i use is to stand more or less where you know the update should come, and run in small circles widening the diameter as you run.
Lag might also be a factor in getting the updates, using more than one toon could help. Have one on follow as you run to get updates has worked for me before.
