When I was checking inside the woodland mansion, i notice that when a Vindicator is attacking a mob they will sprint fast equivalent to a players sprinting speed but instead they sprint slowly on carpets and when they are out of the carpets, they will be back at their normal sprinting speed.
Thank you for your report!
