SteamDB is beeing prepared for a Hotfix for Patch5.
But no Date has been anounced yet.
Guess that Patch 5 introduced so much more Problems that it takes awhile to get them fixed propperly.
But so far even when Larian introduced some setbacks in new patches, the overall vision is clearer and things go in the right direction.
Game still gets better and bugs will be ironed out evtly.
