I’m seeing the same exact thing. I have a simple map I’m playing with where I wanted to spawn a guard when a button is interacted with.
I made a guard spawner with “Guard Team Option” set to “Team Wildlife & Creatures” plus “Guard Type” to “Random”. When I push changes, it defaults the “Guard Team Option” back to “Team Index”. The guard spawned ends up on the same team as my player, and I’m unable to damage them.
Strangely enough setting the same guard spawner to “Guard Type” “Shadow” did fix the problem. When I pushed changes it registered the correct “Guard Team Option”.
