' Deadlock detected' when fighting exiles in Smugglers Stash nodes in Delve

Steps:

1. Navigate to any 'Smugglers Stash' node in delve and start the escort
2. As the cart reaches the end and the exiles spawn, attack them (it's been hard to tell if it's a specific exile that causes the issue)
3. The game freezes and after a while the 'deadlock detected' message appears on screen

Some notes:
1. Sometimes letting them run around for 10 seconds and then attacking doesn't cause the issue but it's still around a 50/50
2. Playing Static Strike and Smite of Divine Judgement with permanent knockback via Blunderbore, if relevant; freeze occurred when using either attack on the exiles
