But, you know, it also doesn't hurt to do that if you do it, it's fine.

Another cool thing about signals is that they can have error messages, so there are certain situations where the signal will flash yellow, and when it does that, that means there is an error with the current setup.

And you can just interact with the signal in that case, and it'll give you an error message and help you diagnose what the problem is there.

I'm not going to go through all the error messages, you guys will no doubt run into them as you play, and hopefully they'll be descriptive enough to help you solve the issues that are on the track at the time.
