There's a button that pops up next to the destination to go there - looks like I need to make it more clear. Thanks for checking it out!
Yes, I realized what was confusing you! You are limited by your speed stat how far away to go, and it's not showing the button because it's too far away.
I'll change it to show the button but deactivated, and tell you when you highlight it why you can't click on it. There will be a new demo tomorrow if you want to check it out again.
