I'm also using a 2 day respawns mods.
There's a bandit area with a campfire and a bunch of treasure chests north of Raven Rock that respawns incorrectly. The treasure chests respawn, but the bandit spawns never happen.
Fort Greymoor: bandits aren't respawning in the fort. The bandits outside the fort respawn normally.
Is there any command to force an exterior to respawn? I know there's ResetInterior for an interior cell.
