Started getting the strangest error when testing my game in Flash CC (Air for iOS 3.9 and tried with 4 beta):
"Test Movie terminated.
The content cannot be loaded because there was a problem loading an extension: Error: Duplicate platform iPhone-ARM found for extension com.adobe.ane.gameCenter"
It was working fine until I tried testing it on my device through the Publish command - Flash CC crashed, and ever since, it's been giving me this error and it refuses to compile (unless I don't use Adobe's Game Center ANE 1.3). It could be the ANE that's bugged, but I can't find a download link for version 1.2.
