Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Scripting Enemy Cowering and Fleeing on Combat

Fixed the issue, or at least found a good workaround:

I created a copy of the character which was set off-stage in the INIT section:

SetOnStage(CHARACTERGUID_UndeadTeresa_001_a2286b44-f384-423c-88d4-2a5fc6c217e6,0);

Then, after the dialog I removed the character that was involved with the conversation and added the copy (In the KB section):

SetOnStage(CHARACTERGUID_UndeadTeresa_5283cab8-a5c5-4a9e-898e-028e77e40d22,0);
SetOnStage(CHARACTERGUID_UndeadTeresa_001_a2286b44-f384-423c-88d4-2a5fc6c217e6,1);

You can briefly see the disappear and reappear, but its much preferred to an enemy who runs from combat.
