So, every casino I have ever tried to build a heart stopper on usually 10p!

I have always multiwindowed it to build the hearts quicker.

Apparently there is a risk that the hearts can just vanish, if you multiwindow.

Happened to me every other time I tried it on any other casino.

Have you experienced this? I know some streamers have had it, while others have multiwindowed much more than I have and never had it happen?

Very annoying.
