So, i was training my wyvern pet and i was playing the dance game, i failed twice, so i got just 3 out of 5, so when game finished it said ''Your pet has not improved'' and it actually did, i got +2 for agility i think, but it said it didnt improve, its not annoying, but i think it should be fixed, i dont know if it happens in another minigames.
Is there a chance your stats are already maxed out?
If your game increases say, Strength and Intelligence, but the stats are alrerady maxed out, then your Exp will increase, but it'll say your pet has not improved, because he can not get more than max in the stat.
