Today I matched 5 black gems with one permanent involved that leads to another 5 match and I got 2 swaps instead of one. This happens somewhat often and is not bound to an event and in every single occurance a permanent was involved.
This issue should be easily reproduced and was already reported more than once here in forums and ingame.
Today my Opponent got 4 extra swaps because the permanent support was involved in both 5-matches.
Not to mention the cascades my opponent got. Gregs only way to win a match? No, he lost it.
