I attached the FollowerEntity script to my soldier and it causes him to fly up in the air as soon as I hit the play button. I know it is the FollowerEntity script because I did debugging and found that when I disable the FollowerEntity script the soldier does not move when I click start.
I actually restarted my project from scratch, so there are not many other variables here. I created a new project in unity 2022.3.30f1 and I created a (currently) flat terrain, imported just the soldier, and a simple script that tells him to walk to a rallypoint. I know its not my script because the soldier still flys when I disable it.
