Last day i lost again the whole setup of all my intanced ai bp.
For reproducing:
Make a parent AI, or character BP. Then add a few variables to the construction script.
The variables are editable.
Now make instances of this bp.
place some of those intanced BPs to the map, then change the values into the instances.(those you placed to map)
Now save all and save map.
Restart editor
Now open the parent of the instanced BPs, and add more editable variables to construction script. Also add some code to the parent bp event graph.
Don’t touch anything at the map and save all, save map.
Now restart pc.
open editor again and see that all instanced BP are set to the default seting of the parent BP.
This not hapen all the time!!!
So continue with add code and variables to the parent bp. save all save map, restart pc.test again.
Do this as long the error not hapen. I’m sure, you will hit the error, once you do this, again and again.
(This is not a jocke! but the error hapen randomly and the only way to see it, is to continue, to add stuff to the parent, aslong the error not occure.)
At least, if it hapen into a large world, you could destroy the PC and trash it trought the window. Really, it is a pain if it hapen.
Not sure, it have to due with the time your project was open. Last i got the issue, my project was open, longer as one day.
