Pressure is not transferred diagonally

Water won't get into second shaft on Level2, but it should.
Pumps also do not pump through diagonal shafts. Water can sip through with normal move, but pressure model does not check diagonal spaces. Easy way to drop pressure without the use of pumps.

Do you have a level 4?  Because water does not search for places to teleport on its current z-level:

Anyway it's just an simplified illustration. I actually had a huge reservoir (20 z levels) with a tunnel at the bottom with a single diagonal joint like this:
Code: [Select]
Note: this is NOT a side view
####
+++##
###+#
  #+#

When water was allowed to this tunnel, it filled one section of it in an eyes blink (as expected) then stopped at the joint and continued to slowly drip there as if  not pressurised. And never rised higher than bottom level. I WANTED MY FOUNTAIN!!!1!1

So, when I closed the floodgate, drained the tunnel and removed the corner tile like this:
Code: [Select]
#####
++++#
###+#
  #+#

it started to behave as expected.

Yeah, this is

Req461, FLOWS AND DIRECTIONAL CALCULATIONS, (Future): Certain flow calculations still only run in 4 directions.


Not sure when I'll get there, but there are some things that need to be handled.
