Jess G. e-mailed STS telling them to give me my plat. She said the game was Pocket Legends instead of Arcane Legends, but I'm sure that will be fixed right away.
I was starting to not like W3i/NativeX but now I'm pretty impressed. It did take 10 days and 2 emails for them to respond, but then they replied to my further emails very quickly.
I was worried that since it had been over a week my platinum would not be given to me, but apparently that doesn't matter if you contact W3i.
+1 to W3i.. as long as the plat makes its way to AL instead of PL.
