what exactly is happening when i "load invalidation" on UI screens ?
There is a button next to update metadata.

Use is for example:
Partner has created a BO and UI on top of it, now a change is made to the BO and this is reflected in
UI Designer, but in the frontend UI the change is still not reflected, in such case you could use this option, so that the UI load is generated and the changes from UI designer is reflected in the frontend UI.
