Updates: I've tried to reproduce the issue with Chameleon build in between stated last known working version (r1242) and the version that causes the issue (r1518) Test results: Highest version that works before the issue occurs is r1516 Only the most recent build (r1518) have this issue. I'm not sure of the changes committed to this build but I hope this helps. Cheers.
