Hi everyone
All of the sudden, none of my NPCs work and I get an errors that say

I did not make any chances to anything, I just loaded the project and this happened. Can't seem to figure out even what it wants from me

Hi,

Nothing breaks without changing anything. But don't worry -- we'll get the project working again!

Are you using version control by any chance? If so, can you review the latest changes in version control and identify what changed?

What Dialogue System version are you using? You can find it in the Welcome Window or in the file Assets > Plugins > Pixel Crushers > Dialogue System > _README.txt.

Can you:

1. Back up your project. Make sure the backup is good.
2. Import the current version of the Dialogue System. You can import it right on top of your existing DS installation.
3. Try the scene again.

If you get the same error, click on it in the Console and paste in the details just like you did above. The line numbers will change, since it looks like you're on an older version of the Dialogue System.
