Every time I try to set an environment query in the defaults tab of my pawn the engine crashes immediately.
I’m following the steps from this tutorial: unreal-ai-tutorial.info, and I have tried several different versions of the engine on github, as well as the 4.6 preview.
Here is the callstack from my last attempt (this was 4.6 preview)

And here is a dxdiag, if that helps at all.
