Where is loading blocks part is done?

[Anke]

The blocks area did not load properly. Changes to the blocks for screen 5475942398296064_menu will not be saved

My way of doing it Notepad++ Install xml plugin 7Zip (no need to rename aia to zip etc) Loading the project in MIT Check count of blocks for the affected screen Check count of <block in *.bky file [bild] Search for in this case for block 4977 (this is where the first issue starts and it might be more) ^(.*?<block ){4977}\K [bild] And as mention above [bild] And you are done.. Edited, Knowing that it is an extension that is missing then we can follow this
