can any1 tell me wad's happening to this....
both of my char and elin used up the treadmill and bicep exercise
to increase 2% of my exp , however i can't use the 2nd time , it's
say "reached the train upper limit , need to be upgrade"
so any1 is kindly help me solve this prob?
or teach me how to upgrade it plz xD

the thing is that those items can only be use *once* per level.. so you only get 2%, you must do the other 98% to get to next level before you can use again

oic....i thought there is a bug or prob xD
