Building lights doesn't work after restarting the editor
Since the migration of our project from 4.11 to 4.12, we have a problem with lights building. When we build the lights everything works as expected. We can then PIE and all the lights are builded. But as soon as we close and restart the editor, the previous building is not saved and the message "lighting need to be rebuilt" reappears.
We tried a lot of things but nothing seems to fix this. Is it a 4.12 bug or are we missing a step?

We finally found the cause of the problem: it was some BSP that we migrated with the project. After removing and adding them again the lighting build stay in place after an editor restart.
