few blocks are not saving some times even after save project it feel like deja vu 
other problem i notice about downloader component i have 2 screen in my app
screen1 downloader cann`t download the image it stop at 100%
while other screen 2 downloader download and save the file
both have same blocks
This can be the problem of builder only so I think that @Krish should see this problem
blocks not saving sometimes so please fix it @Krish
i am facing the same issue even though i save manually my project the last changes i make do not get saved
