I have a recurring crash in the editor.
Broadleaf01 is my most recent addition to the level and probably causing the crash. It’s a Speedtree asset and is casting a realtime shadow on the assets I’m trying to move.
I went to nudge WaterPool2, Bridge14, Bridge11 and Bridge26 to cause them to regenerate their shadowmaps. Initially I was able to move WaterPool2, Bridge11 and Bridge26. Moving Bridge14 crashed the editor. Now upon reload moving WaterPool2 at all causes it to crash.
After 4 or 5 crashes I left the editor open while typing this post and now I can move the assets, so it might just be a just-after-load thing.
