node-orm2 : How to get autofetch working with cache?

For example if you have this kind of relationship : "Post => Message => Vote" with autoFechLimit = 1 in Post and Message.

If you get Post it will fetch and cache Messages too. But then if you get a Message already cached the Vote will be undefined... The problem only appears when cache is enabled, if disabled the autofetching works as expected.

It's possible to force fetching from a cached object?

I need your help :)
