Forbidden doors just don't care

Same reporter. HawkC120 confirmed the issue was not present when he went to test it.
Now labeled as inconsistent.

I've figured out how to reproduce this issue.

Here's my test settlement. There's 3 entrances to the building. At the top there's a single steel jail door. Bottom left is a vanilla wooden door and bottom middle is a cloth curtain leading to two more cloth curtains. When all of them are forbidden, nothing goes wrong, the colonist obeys forbidden doors.

So what happens when I unforbid the jail door only? This is where the issues start to arise.

The colonist wants to go and haul these granite bricks but the jail door is far away and they'd have to take the long way around. So they decide to go through to forbidden curtains.

But once they pass through the first forbidden curtain, they become stuck and can't go anywhere. This has happened a lot of time in my games and I've had colonists starve due to this.

Here's another example. Colonist wants to go haul wood, but the wooden door is too far away so they path through the forbidden door.

With paths and path costs enabled.

Whatever is going on, it's weird but at least it's reproducible and consistent of an issue.

EDIT: Animals share this behavior.

Should be addressed in #23 - can you give that a try?
