Hello, I would like to ask a question, that is maybe a little silly.. :/ I autotrained health points for my pet, but gain only 1, instead of 22, that is showing in sidebar o.O is it normal? :D (I dont buy CSC and gain them only from Bathroom, so 25 CSC is pretty big lose for me :()

Are you looking at the Battle Pet widget to see if your health went up? If so, it can take a while to update and it's nothing to worry about.

If instead it was the event you get at the end of autotraining that said you only gained one point of health, I would file a ticket.

in "event" tab I have a notification "Captainess has gained 22 health points at the Training Center!", but I gain only 1 health point from this training (had 330, now its 331)

Definitely send in a ticket then. A UA will be able to figure out the problem.
