Astar Path Script not showing in the inspector


I’m having an issue after upgrading Unity from version 2017.1of3 to 2019.1.8f1… I know it was a bad idea to go that long without updating things…

The issue is as follows: The Astar Path script is not expanding in the inspector window. It is unreadable, and squished into a single line… I can’t adjust any of the properties.

I tried upgrading Astar to a newer version, but it breaks a whole lot of things in my game. When I upgrade Astar none of the scripts in the game are loading… I can’t get rid of the errors, so I’m a bit stuck here as well.

If there is an easy fix for the issue I am having, please pass along some advice on how to fix it. I would really appreciate it. I am hoping that I can avoid rolling Unity back to the previous version, or rewriting a lot of code.

Thanks ahead of time for any help,

    Fixed a bug in the A* inspector that could cause the inspector to log errors and look weird in Unity 2018.3b5 and up.
