Sanitarium installed fine and there were no problems until now. I just loaded up my savegame from Chapter 2 and found that I can no longer enter any buildings or cross over the stream to the pumpkin patch. Nothing happens when I try to get my character to do these things, he just stands there at the doorway or at the edge of the river. Reloading the save doesn't help, nor does exiting the game and starting it up again.
Looks like I'll have to load an earlier savegame and hope the same thing doesn't happen again. Just thought I'd mention this and see if anyone else has had the same problem?

I know the post is old but this is an original engine issue that was fixed with patch 1.01 of the original game engine. Doesn't GOG version uses the patched one??

I am having this exact same problem. Are there any solutions to it?
