I have lost the ability to use "sub tokens"

So I used to be able to use a token that looked like this:

[node:field_reference:nid]

I'm not sure if they are technically called "sub tokens", but that is what I was referring to them as.

The 'field_reference' field being a Reference module field. This would basically turn into the node ID of the node that is being referenced. I used them both for user and node references very successfully a few weeks ago. My primary use was for Views built with the Entity Views Attach module so that I could basically have a view automatically added to a node that pulls in data based on the reference.

Sometime in the past few weeks, I updated modules and now these tokens seem to have stopped working. I don't even know which module actually gave me this functionality (was it Reference or was it Token on it's own?).

I'm hoping someone has some guidance or suggestion for me.

Thanks!
