Sometimes i get this warning in my log. It does not cause any problems when i launch my game, but should it be something i should watch out for and fix or is it fine if i leave it?
there’s somewhere a missing property. There may be conciquensis in game 
Thats probably a (long known) bug in the Engine, if you’re using a C++ Class inside a BluePrint.
If this happens, just recompile the blueprint, and ignore it.
