Wolves Are Disappearing

Hello! There's a recent bug i've noticed. My wolf disappeared and I have no clue where it went! (It was sat down.) I was going around my house, and I saw my wolf and my ocelot; chilling on the carpet as usual. I went down my ladder, and I noticed that my wolf disappeared. Poof! My ocelot was still there, however. Can you look into fixing this when possible? My wolf was spawned using mcmmo. Thanks!

These wolves were spawned in with the mcmmo plugin, if you notice once they spawn in it says they have a certain life span. The life span seems to go longer but is not infinite. If you would like them to stay forever, you will need to find them in towny wild and tame them. Then tp back to your house and they will follow.
