As I was testing the features added for the Warden, and specifically the new feature with the Warden bypassing shields, I realized during the test that the Warden froze and stopped being hostile towards me. I have to mention as well that I was in Survival Mode the whole time and the Warden was not summoned using commands but with spawn eggs. I tried to replicate this bug after it happened but I couldn't figure out how. I took a video of what happened for clearer explanations (See attachments).
