Hi. Yeasterday i bought faster injury recovery. But it does not say what is the price for injury recovery, only credits. It should to be write what is prize .. i suprised when my money go out..

If you have a level 3 Health Centre, you should be able to see the healing cost each time before you conduct the healing:

I guess you just didn't read it carefully Su?!

haha protein I'm blind. I have been there but don't seen xD THX

To be fair I didn't notice it either when I healed a player the other day.
It is actually a bit deceiving because every other piece of text is in bold but the healing cost isn't.

Level 4 you can heal 50% with one step. The cost depends of the players skills, age, weekly wage and injury depth and so on.
