Flood!

[Leon Trotsky]

This just happened to me, but regrettably I didn't capture a screenshot.

I built a borehole in the last tile of a river (the one where the river reaches the coast) to avoid wasting any energy. As soon as the terraforming was complete, the zone was all messed up! Some land turned to ocean, some ocean raised, any terraforming was lost in a five tile radius... I'll be more careful with rivers from now and on.

THats just odd. Are you sure it was the borehole and wasn't the impact of previously announced searises-- The most I recall my boreholes doing is changing the aridity of nearby tiles

With searises, there is a concept that we have referred to as washing. Its where the land would be immersed due to sealevel rises but is then pulled back out of the water diue to adjacency rules

Consider if 150m is adjacent to a 1300m tile and the sea rises 200 m. The 150m tile would be immersed but that would then render the coastal tile at 1100 which is not allowed. So the 150m tile would end up with some positive elevation but all its terraforming would disappear.

You don't actually get to see the tile immersed but you would see the impacts. Often they will occurr over an area of several tiles

[Leon Trotsky]

I have been able to reproduce the sinking, but not the washing. Just finish the borehole west of Free Drone Central and see the land lower.

[Leon Trotsky]

Update: If Freedom's Foundry is raised before the completion of the borehole, all units and improvements along the river are wiped out.

Its global warming, the land under a borehole that disappears when the borehole is finished says endangered.

[Leon Trotsky]

So that is what "endangered" stands for? I never knew what it meant.

Sorry, I couldn't hold..

"Endangered" are all those tiles that are gonna be submerged after all sea rises triggered will have taken effect. That is, if you get a message "sea levels will rise approx. 66 m", then all tiles 66 m and lower are "endangered", and will be either submerged or washed.

[Leon Trotsky]

Thanks for the information. And binTravkin, I'm glad to be of service, at least as a comic relief.

In any case, why would the completion of a improvement trigger the sea rise? Also, isn't a bit odd single tiles being submerged?

[Illuminatus]

Completion of borehole does not trigger the sea rise. The sea rise is already in effect over whole planet. Tiles are submerged depending on their height - if a 22 m tile is surrounded by high terrain then the 22m tile will be the only one submerged. You've already caused enough ecodamage for this sea rise.

[Leon Trotsky]

Do boreholes lower the tile on which they are built?

[PJayTycy]

I don't know for sure, but in one of my pbems I too got a "base submerged" message in the midst of my former actions (which I always do first). It wasn't even one of my own bases. (oh, and I was certainly NOT lowering terrain. If anything, I was raising terrain all over my continent)

[Leon Trotsky]

That is what puzzles me. In the game I attached, you can trigger the disaster in the midst of the turn; I thought those happened only in the "upkeep" phase.

I was playing a game on the large real map and had the EXCACT SAME experience only yesterday. I'd never seen it before but it was interesting.
