boolean are always false even when set to true !!!

in my game I’m relying on a set of booleans to control Logics such as spawning bosses or opening portals to move between levels. And everything was working until recently, but two days ag,o some problems started happening and now it seems like booleans are always set to false even when I am specifically giving them a true default value .
nothing works in my game right now, please help !!!
I did not add Plug-Ins, or any new assets.
What could be the reason?


  • something else sets them to false
  • you’re observing value(s) of another boolean variable

Watch this value:

You’ll see that it’s True. Don’t forget to choose the appropriate object instance to debug.

I originally had an array of booleans and I was working with it but the problem happened.
then I switched to individual booleans, then the problem happened again
now I created a new Boolean and it work but it will probably stop working tomorrow or after tomorrow.
I think there is some sort of corruption either in Unreal Engine or the project and I don’t know how to fix it
