Black textures? Destination display has double lines?

Do you encounter either of these bugs?

• Parts of your bus has black textures
• Destination display has double lines (see image below)
  

How to fix it?

It's actually simple. In most cases you can despawn/remove the bus (you have do unset the schedule for that) and then spawn it in again. There used to be penalty by BCS for this, but this no longer happens so you can do it without worries.
