NullReferenceException when using Tile Palette #361

Closed phllpbll189 closed 1 year ago

When I try to paint a tilemap with the tile palette open in the side It throws an error every time. I have tiles selected and the brush active as well as trying to edit the prefab. Here is the error.

So I removed it a third time and reinstalled it. Also I switched from the default brush to the GameObject Brush. This allowed me to paint into my tilemap. Not sure if this will help anyone but I sure hope it does!

@phllpbll189 Sorry about this issue! Would it be possible to share which version of the Unity Editor you are using when you faced this issue? Thanks!

If you could share more details by filing a bug report with your project and posting the case number here, that would be great!

@ChuanXin-Unity it was on version 2021.3.6f1. I'm now on version 2021.3.20f1 and haven't run into any issues!
