Skysect: What about Wanderer Outfit DLC ? I already installed everything from scratch and nothing changed . Before release of Overkill Edition even I don't install GOG version of the game . I only bought it for support your company and DRM-free gaming but seems not working as intended .
EDIT : Also if Wanderer Outfit is not working with GOG version , I am not sure about other outfit DLCs too . But I can't test them because I lost my old saves .
The Wanderer Outfit was an Early Access item. Apart from visual appearance, its attributes are exactly the same as the Cavalier's Outfit.
http://victorvran.gamepedia.com/Outfits Edit: I don't understand your question about the maps. They are the same on Steam and GOG. Every version has the Motorhead_Hub and the Motorhead_Tutorial_Arena. You don't start from the Tutorial in Motorhead if you have already completed the Tutorial in Zagoravia.
SSder: Please fix that issue. My game crashed because of that when I tried to play coop.
Krasimir2.0: You'll have to download the updated game installation which is already on GOG from your profiles. If you have the old game version and install the DLCs - this could cause the problems you are experiencing. Another player in the Change log topic had the same problem.
Enburi: Nope man, I downloaded it 2 times in yesterday. And it's still same. Somethings wrong with GOG's DLCs.
This is weird. Could you check if you have some crash logs in your %appdata%\Victor Vran folder and send them to support@haemimontgames.com
Could you give an example with steps what you do and what happens?
P.S. We're preparing a new patch at the moment but I can't tell if that will have a fix for your problem because it may be something new. Have you tried installing the latest video drivers as a troubleshooting step?
