Okay, so yesterday I started a new character and I have the mod alternative start and I chose to start as "Being left for dead". I was then spawned in front of a Thalmor outpost near a border and I had roughly 20 Thalmor trying to kill me at once. I died 4 times before I was able to get away. Talk about a troll.

Lol, wow. Tough way to start the game! I used that mod for awhile and enjoyed it, but since have switched to Skyrim Unbound because it allows you to be unDragonborn.

strange...

I use Live Another Life, Alternate Start every time. I used the Left For Dead start with my thief Kaileena. She spawned next to a dead khajiit on the road between Whiterun and Markarth.

Why would thalmor be aggressive? I wonder if you have a conflicting mod...

are you telling me that all skills revolving around sneaking and survival ONLY failed you 19 times?

as in civ games, you ONLY ONLY ONLY tried to get away with your life, but, somehow, you were thwarted by the computer a.i. of skyrim?

It sounds like you started too close to the north side of Northwatch Keep (in the way northwest,) if not actually within the walls; the local Thalmor troops don't take kindly to that at all.

I wonder how many different locations and scenarios the mod will cycle through when you select that option.
