Thanks for the feedback! The character portraits should scroll if you drag them up or down. Some of the characters don't have jobs and only attend the table which gives you more xp for cooking for them.
When a character is set to get resources they should move to the castle entrance and then back to their station which then adds the resource. If they are not it's likely they are waiting at the table to be served.
I think the issue with the camera is that it might be locked when following a character and unlocked not following, it becomes unlocked when you pan the camera with space and left mouse button like in a paint app.
Apologies for the bugs you've encountered. I worked on the game solo and have already fixed 4 or 5 of them including ones you've mentioned, pending next update once the jam is over :]
I appreciate the feedback
