When I launch into my map and try to use the Camera, It crashes my radiant. Every time I use Radiant I have to use it without the camera mode (3d mode) and its quite annoying because I need to see everything when editing the map...

 I also get a Error after quiting the Radiant map edit with the Camera on, The error says

SANITY CHECK FAILURE

(pdevice)
C:\Program Files (x86)\Steam\steamapps\common\Call of Duty Black ops III\bin\radiant_modtools.exeDevice.cpp:395

Can I get some help, That would be great Thanks!
