No matter what rules I tried, I couldn't solve this problem.

Could you please make it possible to killed Scarecrow while this setting is set to True?

hi, fixed in the next update.

change

if (player == null || Interface.CallHook("CanMarkEntityHostile", player, duration) is bool val && val)

to

if (player == null || !player.userID.IsSteamId() || Interface.CallHook("CanMarkEntityHostile", player, duration) is bool val && val)

I haven't tested it yet, but LOVE <3
