"Uncaught TypeError: this.easing is not a function" when project is opened

[andrew-welsh]

We've been running into an issue where early in our project tween.js will throw this error. The type of tween doesn't seem to have an impact on whether or not it is caused, and it happens from different points in the project at different times, but only ever once. Tweening in the project continues to work fine after this error is thrown. Directly before the error is called this.easing is equal to 1, but before and after this it is equal to the function that it should be. Any ideas why this might be happening?

Do you have an example project that can reproduce the issue?

[andrew-welsh]

Currently we only have this project as we've been hard at work on it, but I can attempt to recreate it in another project later
