Problem description

When calling the function "set animation", about half the time the object will repeat the animation after it has completed even if the looping boolean was unticked. This seems to be completely random as to whether it will repeat or not.

You can see here in this video, the doors should only shake once like on the first and second button click, but on the 3rd button click it shakes twice.

Steps to reproduce

1. Run the project
2. Click the button and see whether the animation repeats
3. Repeat this process at least 10 times to see if it happens or not as it is completely random

Observed result

You should notice eventually the animation loops twice or maybe even more times after clicking the button once

Expected result

It should always only ever play once unless looping is ticked
