I have lost all the blocks I had created for my new app. The app had 2 screens and ALL the blocks of the first screen have disappeared. Can Thunkable recover my blocks? my app name is Tiger. I am a pro developer and have been paying the monthly fee of $20 without using this until now. I have been a MIT AI2 developer and never had an issue of this magnitude. ---

Hi there, Just a quick question. Have you ever tried to refresh the Thunkable X or launch again your broswer to see whether got a bug or other? If your block still disappear,is it show a white screen to cover whole site? Thanks. ---

When blocks disappeared I saw a white Screen1 - with no blocks. I closed and relaunched Thunkable X - no blocks came back. Today, I tried right mouse click on Screen 1. Only option shown was Undo. I clicked Undo and blocks from Screen10 (my second screen) popped in. Blocks from Screen 1 still not shown after that. ---

I think this is whats happening. The block editor has a bug that lets you select Undo when no changes are done. If you make 1 change and then do 2 undos the whole screen clears up. At this point you have to remember to do a Redo before doing anything else. If you exit the block editor without Redo then you lose everything. ---

This is a pretty nasty bug! The same thing happened to me yesterday and I lost everything I had built out for the screen. At least I was able to find this post to see that I am just screwed and need to start over. ---

@dro, Was the disappearing blocks that you reported here due to the issue with “undo” that you mentioned later in this thread? -Mark ---
