I am on small Nitrado server on Crystal Isles and everything was going well, but overnight some of our tamed Crystal Wyverns stats have been reduced by a significant amount, but not all of them. The server has boosted stats and stat gains, that's for sure, so it could be something to do with the increased stat gains bugging out.
I contacted the server moderators and the same thing happened to theirs. They aren't sure what casued it at all. I'm currently trying to help the moderators figure out what caused it. They confirmed the server hasn't been offline since the 17th.
