Yes, I can see someone thinking they are being helpful killing something that looks to be attacking you. Also it has no tame progress or torpor indicator like when you normally tame an animal (at least that other players can see). It is not knocked out on the ground either.

I would suggest for now, if this is your server where this happens, make a rule to not kill or start a tame near other players. Players should only do taming and killing near another player when invited. This solves many problems, not just this mod. I've seen the same happen with other mods like Shiny Dinos. In that case, one server made a rule you must type in global anytime you start a tame. No one on that server is allowed to tame or kill a shiny dino without writing in chat. Of course, there are typically not more than 5 shiny at one time, so that won't work for immersive, which literally applies to anything that can be tamed.
