Can confirm this is also happening on our fresh-wipe 42.19.0 server.      Respectfully, for the MP team, this desperately needs a hotfix and cannot wait until patch.   This is going to absolutely destroy multiplayer until it's hotfixed. Nobody wants to play 'Project Zomboid' without the 'Zomboids'. 

Hey MB, Thanks for the reply and for the warm welcome. Fortunately for both of us, I was able to confirm that the Teleport menu is working correctly via Debug after following the steps you listed above. I really appreciate your assistance with this topic. Wishing you a great rest of your week and an even better weekend. Cheers - Nox

Version: [42.19.0] Mode: [Multiplayer] Server settings: [Dedicated] Mods: [None] Save: [New Save] Reproduction steps: 1. Load in with 2+ people 2. Activate Crouch and begin walking around / hitting zombies 3. Other players see the "crouch walking" player teleporting around and generally being weirdly desynced   4. Uncrouch and sync returns to normal, other clients see that person walking around and hitting zombies properly again Fully fresh vanilla zomboid client, Zomboid folder in my documents also deleted and allowed to re-generate, no remnants of old mods in my client at all. Issue did not happen on previous patch with the same players, its not a lag/latency issue

Thank you. 🙏☺️   Indeed it is on the list. Huuge thanks for adding the logs, video, and the ARF data as well! 🙌☺️ I was able to load it up and everything's in the right place. Basically eliminates a bunch of modules from the list of suspects, and narrows it down to the action queue system. I shall dive into it just as soon as I get on top of some critical tasks first. Big thanks again. ☺️🙌

You beauty! Big thanks for including the logs, video, and making the ARF for us. ☺️🙌 I've just loaded up the arf and it looks like this:   The AnimGraph appears to be working correctly. Note how we can see the character is wandering around and coughing and sneezing. The MedicalCheck appears to get stomped higher up the path, in the action queue. This narrows it down a great deal. Big thanks again. ☺️🙌
