I have a BUG will cause the game to crash in the AI BTT file

Hi,
I was doing an action game,when I update the unreal engine to the 4.7.2,I found a BUG will cause the game to crash .Whenever I modify the default value of player_BP or AI_BP, at the time the game running my games will crash in a BTT file.But if I modifythe default value then save restart, will not crash .It happened in the 4.6 version never had.
If anyone knows why, please let me know.Thank you.

I’d love to help, but could use some more info. Like callstack, logs, repro project. Basically anything you could spare.

Cheers,
