Added a fix on the barrier message buttons.

In the adaptation of some mechanics to browser I used the same button to open and close the message of the barriers, these read independently that caused a lock in the game, the button that closed the message also opened again.

I made some immediate corrections and I’m reading the code to look for more points like these.

I am working to bring the best possible experience within my capabilities and limitations.

Thanks for following the Criatures project.
