Impossible to drain water off map underground now?

[BoogieMan]

You used to be able to drain water off the map by carving the tile at the edge of the map into a fortification. This was extremely useful for artificial waterfalls, so you could have the water fall as far as you needed, and then have a drainage tunnel to the edge. Now you can't do anything anywhere near the map edge.

This now requires a cavern layer with water that reaches to the map edge naturally, or just an open area of cave that leads off map. However, this is bad for FPS by making the drainage spread over a huge area.

Anyone know of an alternative, or how to disable the map edge restriction?

You still can, I just did it. You have to smooth it first and then you can carve a fortification.

Hmm, I wasn't able to set mining designations near the edge of the map to dig there in order to carve it.

[kheftel]

That's weird. I was able to dig right up until the edge of the map, not including the last block ofc, and then smooth/engrave...

You dig until you can't. Then carve. Always worked that way, and it still work.

I just verified I absolutely cannot mine all the way to the edge of the map. I can't designate mining about 16 tile from the edge.

On the surface I built a road to the edge, but didn't try mining anything up there. But underground, yeah, it is impossible to mine a tunnel to the map edge.

Very strange. Is there an error message, or does designating just fail?

The mining designation ui element, the box you drag around, just won't draw around the edge and clicking does nothing.

That is intriguing. Does the rock change at all where you can no longer dig? Or is it the same type of rock? I wonder if you found some hidden thing underground.

thats just a padding. you can smooth + fortify the next tile behind the last you can mine, that will do it.

Ah, so that's not the edge visually, but it is mechanically. Good to know, thanks!

[kheftel]

Yes, that was sorta what I was trying to say

Just wanted to note that I had an instance where I couldn't do this and it took me a while to figure out why.
When the edge tile (the one you can't mine) is an Aquifer-Tile. Then the game won't let you smooth that one and doesn't tell you why.

You should be able to smooth aquifer tile. That's a way to stop them to produce water. But you can't smooth a non stone tile. Which is most likely the issue you had.
