How to reproduce:
1. Open attached Unity project "FreedomEngine"
2. Select File --> Build Settings
3. Add "teststage" scene
4. Check Development build checkbox
5. Build and Run
6. In the build press Resume
7. Try to run with wasd or arrows

Expected result: Player is animating while running
Actual result: Player stays idle and error "Unity could not produce class with id 1180" shows up.

Reproduced with: 2018.2.0b2, 2018.1.0f1, 2017.4.2f1, 2017.2.2p4, 2017.1.3p3.

Notes:
* This works as expected in the play mode.
* Jumping animation is working.
* Can't check on WebGL because of errors.
