Pitboss question about different versions of a mod

[45°38'N-13°47'E]

So, I've started this pitboss game using Realism Invicuts with 6 other players. So far we've played around 100 turns, most of them in a single session plus some more slowly playing day by day until the next session. Problem is that it looks like someone has a different version of the mod. Which is kind of strange since all players should have downloaded the mod from a link I provided which also contained a couple of fixes for Realism Invictus, and have confirmed doing so. But when I look at the pitboss interface, I can see the warning *MOD* next to a couple of players names.
Now the question is: is it possible that we have overlooked something? Is it possible that the pitboss server shows this difference because of a different CivilizationIV.ini for example? They can still connect to the server, so until now this *MOD* warning is not an issue, but I would like to avoid problems later in the game. I thought that having all players downloaded the same mod from the link I provided, we should all have the same version. Yet, a couple of them have this warning next to their names from turn 1.
Any suggestion is welcome.
Thanks.

If some are playing with disc version vs. steam it will show a mod sign. as long as everyone can connect it is ok.

Also, there are some mods that are compatible with being different, such as Blue Marble.

Thank you guys! Hopefully it's just that and it won't cause issues!

The problem also could be forced by this:

1. Picking a python file used by the mod, e.g. Python\CvEventManager.py
2. Backup the CvEventManger.py from Civ4:BTS.
3. Change the CvEventManager.py from Civ4:BTS.

Now, if you login the PBServer should warn about the different state of the client, but you can still login without a crash.

I thought about disabling the error message in the pbmod.

However, I can't distinguish valid error messages from false ones and would then have to suppress the correct messages as well.
