I’m not sure what you mean. If they supply the entire save game folder, you should be able to simply load that game within your own setup (after copying the save game folder to your own saves folder).
I have only ever had to do some ini tweaking when trying to load a MP game. I am assuming this is a SP game?
Also, it’s a concern if other players are experiencing the same. That sounds more than coincidence.
Try and get a copy of the save game folder off at least one player who says they are experiencing it, and ask them for details on how to repeat your end once you have a copy of their save game. Then load that save and test.
EDIT: I have assumed we are talking about RotE.
EDIT: Do you have a generic “leave” conversation and script reference for your companions I can check? I have your mod open in my toolset, but cannot see anything obvious yet. i.e. What conversation should I check where the companion is asked to leave?
I was trying to open ga_rm_set_hangout and roe_ga_go_to_hangout, but I cannot find them in either the module (that I have open), campaign or global scripts. It may be that you only use then in a certain module, but I don’t know which one. In this case, if the companions can travel between modules, and these scripts are required still, shouldn’t they be campaign scripts? Your setup is different to the way I do things, and I have never tested scripts between modules - except that they are all campaign scripts now in my case, as I was forever getting into problems with module scripts in isolation.
Found the script I was looking for - It was a global … but still cannot find the two mentioned above - anywhere.
