If you create a variable in an animation and then refer to it, a false error about an unknown variable is generated in the log.

Steps to Reproduce:

1. Create an Animation Controller that uses a Molang variable.
2. Create a second Animation Controller that references the created variable.
3. Connect Animation Controllers to Players.

Observed Results:
When connecting to the world, an error appears in the logs (Error: unhandled request for an unknown variable ...). However, it's important to note that this error does not affect the functionality of the code, and it still works correctly.

Expected Results:
The error should not appear since the variable exists.

Example Code:
animation_controllers.json
