Small but important patch this time!

- Visual update to the damage chart.
- Fixed a bug where you might get a duplicated unit as a reward.
- Fixed a bug where you might get stuck in Growver Field if you had all units at max level.
- Fixed an unintended interaction with Guardians triggering their effects on other Guardians.
- Fixed some abilities having a wrong target preview.

Thanks to my playtesters for all the reports!
