Turtle1 not visible in Gazebo (TF BASICS)

Hi, in the course TF, chapter 2-TF BASICS, the turtle1 is not visible in gazebo. When I click on the approximate area that the turtle1 would be, I get a square wireframe, showing its presents, but not visible. Can you share how I should approach this?

Hello @Joseph1001 ,

If you open again the Unit, is this error still happening? I’ve checked it right now and it should be working OK:

If this ever happens again, it should get solved by just refreshing the browser.

@albertoezquerro Thanks, the turtle is visible now and it’s working great.
