Invalid destination?

[DinoTamer]

Once I have the animals on the market, i cannot place them in their habitat (wich is perfeclty defined). The message "Invalid destination" appears. Someone knows what is due?
Pd: The animals are the nile monitor

What do you mean "on the market"? Are you trying to sell them?
The animal has to be in your storage if you want to place them in your zoo. They can't be on the market for sale AND roaming your zoo at the same time.

Fixed! I had not defined the barriers as habitat, my fault.
Thanks for answer!
