Known Bugs

ISSUE: Several prefabs (e.g. Teleporter, Spikes) with custom shaders appear in magenta.
WORKAROUND: Select the affected prefab and pick the Universal Render Pipeline/2D/Sprite-Lit-Default shader in the Inspector. The thumbnail in the Project panel won’t update immediately, but it should look right when you drag it to the Scene panel. 

ISSUE: You immediately receive several console errors that prevent the sample scenes from running.
WORKAROUND: Delete the script file named RuleTileEditor.cs. This has been moved to the 2D Tilemap Extras package, so it’s a redundant copy.

ISSUE: You’ll receive a warning that “The version of Burst used by your project has changed. Please restart the Editor to continue.”
WORKAROUND: After the import is successful and the previous fix is applied, quit and restart the Unity Editor. When you restart, you’ll be prompted to choose another Editor version, so pick the latest 2021 LTS release you have installed. You’ll get another scary warning that you’re “Opening Project in Non-Matching Editor Installation,” but just hit Continue.
At this point, the Kit Tools menu should be visible, and you should be able to run the sample game.

ISSUE: Ellen takes damage, but the HealthCanvas isn’t updated.
WORKAROUND: On Ellen’s Damageable, the On Health Set event is trying to call a missing HealthUI.SetInitialHeartCount function on HealthCanvas. Instead, select HealthUI.ChangeHitPointUI.
