Wolf Update to 2.3.1 fixes a few things in the wolves that you have been reporting.
First up is the sound off in babies 0 to 1 day old.
The large sack issue that appeared in 2.2.7. We did release a 2.2.7c and unfortunately the Updater is having a hard time detecting this version. If you do have the 2.2.7c as your animals you will have to MOOG the animals instead of using the updater.
The reporting aging issue in the Low Prim version is also been fixed.
The Updater will work with versions other then 2.2.7c
