Trying to edit/view PreviewShadowIndicator material crashes editor
The following material (among others) is not compiling properly when I am launching/building for iOS. Trying to open it to view/edit the material causes the Engine to crash every time. This reinforces my fear that this is something to do with my game crashing every time on iOS/iPad Mini (but not Android), but it's hard to know for sure. I also can't delete it, as it is referenced in the Engine script and other places. Thanks for any info!

Try deleting your Saved, Content, and Intermediate files/folders and then re-opening your project and running the 'Fix up Redirectors in Folder' option on the Content Browser.
If that does not resolve the issue, try manually locating the material and adding a 'Feature Level Switch' node into the material, so it auto-detects what is/is not compatible with your mobile platform.
Since this is just a warning, and not an Error which can cause your project to fail to build, I would not worry too much about it. And looking at the crash log you've provided, it also appears your crash is being caused by Widgets and the Paint function.
Can you reproduce this error message in a new blank project under the same targeted mobile platform?
Update: This was a known and reported issue UE-23370, and has been fixed in the 4.11 release.
