BUG: Liliana - Grave Mist with STR

Unknown

Liliana has a bug, where sometimes when you have Grave Mist activated orbs on the field, and you match them, nothing happens. I've encountered this issue multiple times, and through some testing I've found that when activate Grave Mist, then on a subsequent turn, activate Corruption or Raise Dead, the Grave Mist orbs no longer function. This is most definitely a bug that needs to be fixed, as it hinders the players ability to reliably use Liliana.

Steps to reproduce:
1. Start a game using Liliana. Play until you have 18 or more planeswalker mana stored.
2. Activate Grave Mist when you have 18+ Mana stored. Take turn making sure that you have the newly activated orbs left on the play field.
3. Activate Corrupt.
4. Match a Grave Mist orb to observe the bug (The orb no longer works)
