I highly doubt that KovuLKD will ever return back to FeralHeart. With him leaving without informing the staff and community was a definite sign that he didn't particularly care about FeralHeart and/or the community. The person you are probably talking to is another member of the community posing as KovuLKD. Members of staff have tried getting in contact with him nonstop the year he left and there was no answer. Why he left? We do not know. But as said before, in the previous comments, it was his choice to abandon the game, and so it is his choice whether or not to come back, like I and other people said before, it's more than likely that he won't return. Therefore we should leave him in peace for whatever his reason/excuse is.
To be fair, I think we should end the search for Kovu because so far I'm seeing this search as a big 'act' and who ever you are contacting is playing a game many of us do not want to play. Let him come back when ever he wants to, it's most likely he is afraid to come back for all the possible abuse he will have for doing this. Even though he isn't here to do regular updates for the game, you should be happy that the Staff we have now are putting 110% effort into the game to make the FeralHeart community happy even though quite a big piece of the game is missing. All the events they put up for you so we can all have fun, laugh.. I believe its all 10 times better than an update on this wonderful game.
Sorry, but it's a complete waste of your time trying to find this guy. Who ever might be posing him is making you run around in circles at the moment. It's already pretty clear he's not coming back for gosh knows how long. So lets just end this now instead of 'teasing' everyone. Many people have their hopes up and once they realize he's nurturing, they will all be devastated. Don't take this the wrong way, I understand you're trying to help but all this is just quite pointless.
