Hello,
Wanted to share this and what I did to fix it for me.
kept getting an error in UIDrawCall.cs at line 260 where panel was null.
This would happen whenever I would select a new object inside the hierarchy. (Did not matter what I was clicking)
This could be caused by something I am doing wrong, so here is my current Hierarchy setup
UI Root>Camera>Panel>Sprite & Labels
I decided to just throw a tag on the panel and added the following before line 260
if (panel == null) panel = GameObject.FindGameObjectWithTag("Panel").GetComponent<UIPanel>();
Hope this ends up being helpful.
Thanks =)
