When hunting Chromeon in Saipark, if the only Temtem that appears is Chromeon, then the Temtem will walk up as normal. However, if one or both of the Temtem are filler Temtem (in this case, Saipat/Tateru), then both Temtem will walk up, and then teleport a step forward. This only started happening after the most recent patch. I asked around, and it is not happening to other people, so I don't know what it is about my account that makes them teleport. If anyone else is experiencing this, please feel free to add to this post with any details that you might have. I don't have the tools to make a video on this, but have provided screenshots of the positions of the Temtem pre-teleport and post-teleport. Let me know if you require any additional information.
