Sad Honorbound story: When I was new to the game I didn't know the importance of the gems so spent all of them randomly on useless stuff. So only ever had two researchers. So, I've been saving up my gems I've been earning for since I've started the game to buy another researcher but unfortunately I accidentally pressed buy to speed up a research using a lot of gems. Can I undo this???? My characters are all at level 40 and above so I don't want to start again..... Cheers.
