Runescape

A new learning experience. As part of the on-line class I'm taking through YALSA, joined Runescape. I'm still in the tutorial phase and found it frustrating several times when told to use an item that it was nowhere to be found. Such as, copper and tin ore. I was supposed to have successfully mined both, but I could only find the copper for the longest time. Then, out of the blue, there was the tin! Is this normal? I finally quit out of frustration. I'll try again another day......maybe......
