Warning: Unknown property in after changing variable in Structure
I think this should be brought up as these seems to be a bug, after changing some variables in a blueprint Structure the log posts a load of warnings, and these come up every time i compile blueprint that use these Structures, my currently project logs around 200+ lines of these as i have changed/edited or added variables to my Structures.

I was able to get the same warnings in the project that you attached (thank you BTW) and I was also able to reproduce the issue in a new blank project. I've created JIRA UE-30031 and our developers will be investigating the issue further.

I have had lots of problems like this. Definitely bugs. If you can find a reliable way to produce the bug, you should definitely add that here so we can an actual fix.
Workarounds - Sometimes, deleting the variable and recreating it will fix the problem. - Recreating the blueprints that emit the error have always fixed it for me. DON'T duplicate your blueprint. It just duplicates the problem. Create a new blueprint with the same parent class as the one you're duping. Create all the variables and set their defaults. Create all the functions and set their input/output paramaters and create their local variables. Then you can copy/paste your event graphs from the original blueprint to the new ones with 99% of them "just working".

OK I can confirm that its structure variables which are producing these warnings. I just fixed a few by setting the variable to a Boolean then compiling then setting it back to the structure then reconnecting the wires then compiling again. It seems when you change a structure the references to the following structure leave behind the old variable references in memory? so we can class this as a bug as these references should be getting cleaned up in the process, I hope this bug gets looked at as i hate to have to redo all my structure references each time i change the main structure.
Have same issue all the time, but it just go away after recompile and reopen project.
Important note: If you use structure in interface, you need to compile interface before closing project or it would break all connections between structure and interface.
