How do you go from the hub at the windmill to the level?
If such a thing is meant to be possible in the preview build, my guess would be either the gate in the back, or NPC1 down the well, neither of which are working assuming the gate is meant to do something. Either way, NPC1 is broken. Talking to him locks the camera, but no dialogue appears, and you can still move around. In order to fix the camera, you need to talk to someone else. Here's hoping he wasn't an important NPC, or was, so it can be fixed ASAP and content is available as intended.
