It has previously come to my attention that there is a bubble column bug. Basically, any flowing water coming from a bubbly source will stop on the first block that it flows on.

I really want this fixing because it is a pain to make storage systems and it has been around for about a year.

I don't know if anyone has made a bug report on this already if so sorry.

See picture for more info.

P.S This bug applies to all version up and till 1.13
