Trying to play with my partner in local co-op with Divinity Unleashed mod from Nexus Mods.
My version is 2.5.4.2, which is the latest one in Nexus Mods. His for some reason is 2.5.4.4, which doesn't seem to exist at all?
I have tried to update my mod on Vortex and he has done the same, but his remains 2.5.4.4 and my 2.5.4.2. has no updates.

This is stopping us from playing this game in multiplayer, please advise on any suggestions we could try to fix this.
