I tried to pay another pack for art but found that I couldn't send them mushrooms and got the message: "Packs must be actively played to send mushrooms." What does this mean and how do I fix it?

I think You have to have atleast 2-3 wolves in your den for your pack to be considered active. So maybe try and buy some wolves and see if that works

Not sure. To me it sounds like it's either a bug/glitch or they're hiatus or something. "actively played" sounds like it's something to do with them being inactive. Who is it? If they're a former pack then that'd explain it--a formerr pack means their account expired. Not sure though, like I said

Ohh, that makes sense. I really only play to rp and be in the community, so I got rid of my wolves for the hiatus. Thanks for the info.
