Hello, I have the same issue. The good news is that the uasset´s filesize is still pretty big so it seems that the content is not lost at all. How can I save/rescue this uasset widget file…there is so much text written and I would lose days of work on that just because UE thinks it doesnt need it. Holy cow, I really need to stop Unreal from deleting the widgets on opening the widget! @ EPIC GAMES
I worked with source build 4.26.0, now opening a copy of this project with the regular 4.26.1 from the launcher. When I open the widget blueprint first time, I get the removed unused widget message. So it seems to remove it on opening but thankfully not saving this change. I really need to get access to my content.
And by the way, this is not fixed in 4.26.1 since its still deleting all the content on opening the WB.
