I tried collapsing a procedure block, then it became like this
I don’t know how this event block became like this
Blocks downloaded from options menu by right clicking
I duplicated corrupted block and deleted corrupted block
Now it became fine
Yes there’s some problem with blocks recently, It’s recommended to not collapse blocks.
Here’s another one - Bug: Blocks Disappear
Varying ways this might happen, haven’t experienced this myself but from having repaired so many aia’s I have noticed that users are to lazy naming theirs screens, components (x, c, b, y) etc
Importing/ Copying screens
Un- / Install extensions
Bad internet/communication to server
Etc…
End result, broken project…
