Ground Plane breaking on second hit test

Vuforia SDK Version: 7.0.43 - Description with steps to reproduce: I’ve noticed this happening on Android devices and some old iPhones (that don’t have ARkit). It’ll work fine up until the point that the lighting is dark or it can’t find a plane. In low light situations, it will always perform the first hit test correctly, but the second will break it. Just wanted to know if this is an issue Vuforia knows about, and if there’s anything I can do to fix this ASAP. We’ve released our app with the new ground plane feature and this is causing massive issues. Thanks - Development OS (Mac OS X, Windows, Linux): Windows and Mac - Mobile OS and Version: iOS 11 and latest Android firmware - Mobile Device Manufacturer and Model name: iPhone 6 and Samsung Galaxy 7 Edge - Do the Vuforia Sample Applications show the same behavior?: Yes. Ground plane samples do this when it’s dark.
