While flattening a huge area next to the lake I'm bothered by a terrain glitch. Next to a texture boarder it's impossible to fill up or flatten a specific place. Instead of filling this particular place, the soil warps to the quadrant right next to it.
Couldn't find any solution for it, perhaps anyone else fixed it yet?
It's hard to see in your observe screenshot, but soil has a 2 meter slope maximum.
What this means is, if any adjacent tile is more than 2 meters taller than the tile you're trying to lower/flatten, it will pour its soil into your target tile and lower the higher tile by 0.1.
There is actually a current bug where extra soil is generated in this process, so unless you're needing extra soil, it's advisable to lower the higher tile(s) to 2.0 higher than your intended lower tile altitude.
I hate when my English not sufficient enough to describe something
I'm not talking about soil which gliding into the next tile. Look at the first screenshot, I'm looking at tile x and want to raise the level of it but instead of filling tile x up, the soil disappears and tile y growth. This is what you can see at the second screenshot. It's just like there would be a "wormhole" which beams the soil into another tile. So what ever I do, even if I pave tile x ,happens to tile y!
