Creating Blueprint Book causes crash

[schoos76]

When I click on the "Blueprint book" in the dock, in Factorio 0.18.40 this crash happens:

The mod Blueprint Extensions (0.5.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event BlueprintExtensions::on_player_cursor_stack_changed (ID 29)

Same problem here using Factorio 0.18.47 (build 54412)

Also getting this on Factorio 1.0.0. I believe that #36 is also related.

I believe this mod author has dropped off the face of the earth for the time being. :-(

He was on the Factorio Discord earlier this year. I suspect we'll hear from him again.

There's a similar caught-so-no-crash bug in Picker Blueprinter, so I'll be keeping an eye out for the fix over there to try porting over here if no one else does it.
