Hi everyone,
I have noticed a weird behavior of the widget switcher during debugging and monitoring using the blueprint debugger.
I use a widget switcher in my menu with a Widget called “Load Game Widget” to easily change my displayed widgets.
- Setup: Only LoadGameWidget + Spacer Widget
However, I noticed that upon starting the game, six instances of the “Load Game Widget” are created. A closer look using the debugger showed, that all instances except for one have some variable errors (variable value is [Unknown] (Class: [Unknown]))
After some more testing where I wasn’t able to get rid of the other instances, I added another widget to the widget switcher and suddenly more instances were created:
- Setup: LoadGameWidget + Spacer Widget + OptionsMenu
After reverting everything back (I did not change any code or blueprint code!) it suddenly creates even more widgets 
Did someone else also notice this behavior?
I am quite sure that this is caused by the widget switcher (but maybe I am wrong).
Is this an intended behavior/needed for the widget switcher to work properly?
Because it seems like a potential memory leak or at the least a serious bug.
