Editor filling in terraformed ocean

[AvoINFINAUT 0]

I posted another thread recently trying to get help on how I could efficiently fill in the ocean i had drained in the editor, well i was messing around and somehow using the destroy terrain mode with the biggest brush size in the air bubble under water it somehow created water where the air bubble was, im not sure how to replicate this because it wouldn't work in other places but i thought id just share my findings for others trying to deepen an ocean.
