It is almost embarrassing to ask this, but, I need some help with my PIE. (no, not eating it. I need no help with eating pie tyvm.)
Some how I managed to get my PIE undocked from the editor. found an article that said I should delete DerivedDataCache. So, I did. I have tried reset to default in the advanced settings of the Play button. Nothing worked so far.
I REALLY would like to get PIE docked again.
