v2.2.0: fixed a variety of small bugs:

- guardians 'dodging' instead of 'blocking'
- guardians having defenseSkill while recovering
- spire not finishing attacks if hero leaves vision range
- beacon of returning allowing return to mining level
- 'cash out' being repeatedly selectable

 actors.mobs.crystalguardian.desc=These large crystalline guardians almost look like statues, if it weren't for their bright glowing eyes. The hardened crystal they're made out of causes them to be sluggish but very tough, so _it's best to leave them to sleep in their crystal nest for as long as possible._\n\nDue to their size, crystal guardians will move much more slowly in enclosed spaces. They're also so durable that they're impossible to kill outright. They can be beaten down and temporarily disabled, but they'll just get back up again after a little while.
