Doesn't work with 2018.1.6f1

[divs1210]

I get the following error on playing run (and the villain disappears):

A game object can only be in one layer. The layer needs to be in the range [0...31]

Experienced a similar issue with 2018.1.0f2.

Things worked here after modifying some things in the Unity Editor:

• created the player-bullets and enemy-bullets layers,
• set each of the villain and fighter prefab layers to the corresponding newly created layer, and
• edited the Physics 2D Settings (via Edit -> Project Settings -> Physics 2D) so the checkbox for player-bullets / enemy-bullets was unchecked

Have yet to defeat the enemy / villain...
