Garran: What level were you when you first entered Arnika? Were you 6 then or did you hit that after arriving?

Quatermass: I have a level 6 party fresh from the monestary, but keep running into a group of androids that include two level 21 ones. There are 3 level 6 savant gunner droids, 7 level 5 higardi rebels, and 2 21 androids. I have tried fighting with patrols, door way blocking, but I keep getting slaughtered every time.

I have even tried rezoning several times, but the level 21 droids are always there waiting for me. Anything I can do? The game is unplayable for me with these deathbots waiting for me.

Garran: You may have hit a wraparound issue with the spawn system, but I don't have the old lists to check on whether that's possible. I do know that you want to make sure you're at least level 6 before entering.

If you still have the save game then the best option would be to leave the entire area (head out to the road and find a hidden corner) and camp for just over 24 hours (three full periods plus a small bit of a fourth) to see if that resets the spawns in the city.

One other thing to keep in mind: the creatures generally won't follow you into buildings UNLESS they've already engaged, so if you see a group coming you can get inside somewhere and out of immediate LoS of the doorway to lose them. (Pretty much every occupied location in Arnika other than Antone's shop lets you do this - and Antone's will if you go through a door.

Likewise, they can't open doors, so nipping inside somewhere and slamming a door in their face is a good way to avoid trouble.
