Currently if there is a Spark Double copy of a card in play that card would have one counter on it as it should. However if a second Spark Double would enter and copy the first copy it received two counters instead of one as it should, and if you copy that with another one it receives three counters and so on and so forth. This is especially problematic when it's used on planeswalkers as if, for example Quintroius Kand, engeess with more loyalty counters than it should it let's you activate their "ultimate" far ahead lf the curve.
Considering this is a pretty big bug affecting one of the most played decks currently in Pioneer I hope you'll be able to resolve this bug soon.
