Repro:
1. Pick Rubick and create an enemy Ember Spirit
2. Place some Fire Remnants as Ember and steal the spell as Rubick
3. Place some Fire Remnants as Rubick
4. Cast a different spell (Q W or E) as Ember and steal that spell as Rubick
5. Use Fire Remnants again as Ember Spirit and steal it again as Rubick
6. Use Activate Fire Remnant as Rubick


Result: At step 4, the Fire Remnants from Rubick do not disappear. At step 6, Activate Fire Remnant does not use the previously placed Remnants.

Expected: 2 options:
1. Either make Rubick's Remnants disappear once he loses the spell.
2. Or make Activate Fire Remnants able to use the previously placed Remnants.
