Hey.

We're currently trying to do a multiplayer session of DOS2:DE with a GOG player and some Steam players. But we can't play together because the steam version number is 3.6.28.9969 and the GOG version number is 3.6.28.9550. This forces this error:
ERROR
Joining failed: Players have different game versions. Please ensure you're up-to-date!

There is no patch to version number .9969 available in the GOG download files. We're trying to connect through the "direct connect" option, but no matter whether the GOG or Steam user hosts, it doesn't work. Are we missing something or is crossplay impossible right now?
