Looping animation clip stopped after long usage

Hi,

We have an application that has to run over long periods of time (weeks at least, probably months) and we have an animating sprite within the scene that just has to loop it's animation over and over.

We have a controller with a single state change from Entry to a clip that has loop time checked.

It was working fine for over a week and then randomly it has stopped. I've checked our log files and there doesn't seem to be anything showing an error. There is no script on the sprite.

Is there anything I can check for to see if it may have triggered the animation to stop, especially so randomly after so long?

Cheers!
