Anyone understand how the ocean refills itself yet? I'm trying to figured out it's behaviour but it is erratic sometimes. I hate seeing air pockets.
Dont think there is any mechanics for this yet at this point. But i am not sure 100%
If you dig a trench, water seems to flow without limit horizontally (i.e. no need to slope downward like in minecraft). However, the chunk has to update in order for the water to flow or fill in holes. So, sometimes those holes will stick around for a while.
