I am running Unity 4.6.1 and using Vuforia 3.0.9. When I leave a scene which has ImageTargets inside it, and I they have not been triggered at least once since that scene has loaded, the editor crashes. I have attached the log file for reference which shows the crash. Hopefully this provides something to go on. This also occured on Unity 4.6 with the same Vuforia plugin.
Any help would be appreciated. Its easy to forget that this bug is occuring, and the editor crashing can sometimes lead to lost work.
