Hi, Rudy. Few minutes ago Ive suffered this rollback to the default parent values in all my child classes. Came to this thread after searching a bit about the ocurrences. Im currently using 4.11.2. Id like to update this report, that seems to be marked as solved. One thing that Ive noticed this time is that I accidentally pressed the PIE button without compiling my dirty BPs before. It took a longer time than usual to recompile and start the game and, after this, all values were reset. Well, this is kinda frustrating for the developers to think about all the time that have been lost by this bug everytime it happens, but I hope you reopen this thread and keep the efforts for solving this. As a measure of precaution, I suggest everyone create an initialization function and set the values from there, in the construction script.
