How do I keep my Alpacas inside an enclosure? I'm getting " Cannot rope Alpaca: No enclosed pen"

[Laycee]

I'm trying to keep my Alpacas inside an enclosed space. I built a fence area, and a "pen", but I still have 2 problems:

• I don't know how to bind an Alpaca to en enclosed space.
• The Alpaca in the screenshot jumped over the fence. It didn't really work.

How do I keep my Alpacas enclosed?

EDIT

The problem was that the sandbag prevented my enclosure to become an enclosure

Are you sure the area you are trying to use as a pen is actually considered one? Or the Pen Marker you use allows for alpacas in its rules?

Going by your screenshot it looks like 2 visible possibilities: The wall on the bottom is confusing the pen and/or you are missing the fence gate.

I don't know if you have zone highlighting enabled, but if it was and the pen was recognized, it would be showing.
