This might go in the direction of possibly there needing to be some compatibility patches, but as I started using Oskar's Nutrient Paste Expanded mod I finally noticed the animals could not use it and was terribly embarassed to find out I took this mod for granted for SO LONG (Take this as highest praise)

But on removing that mod (because they also change the standard dispenser a bit) animals still can't use it. Unsure at this time if starting a fresh save without that mod might fix the issue. This has been the first time I played since the new updates.

Also, I have noticed some modded animals unable to use the dispenser, specifically some from the royal animals mod from Oskar, but not all of them as hybrids and other beasts can use it just fine.
