Unusual issue after Global warming event

[AMD4EVER]

I had been away from Alpha Centauri for about a decade before stumbling across this site and finding the Yitzi patch.  I wanted to try playing this game again and was astounded at being able to create a 100x200 map and not have the game crash within the first few years.

I've made it to the year 2518 but am having a strange issue.  The easiest way to show this issue is to use Ctrl+K to add rivers / drill to aquifer.  When a new river is added, for some reason it can wipe out all farms and boreholes along the path that it travels.  If you start creating a ton of these then you'll even start getting messages that bases around the world have been consumed by rising waters.  All of this is odd and if it was the only problem then I could live with it by just not performing drill to aquifer.  Unfortunately, even creating condensers or boreholes with my formers can cause similar issues.  Worse yet, when the initial Global warming caused 66 meters of rising waters and the entire map was redrawn to fit the new elevations, I lost farms and boreholes in patches all around my continent.  That Global warming even started all of this

I've attached a save of my game.  The two things worth mentioning are that I greatly modified the starting map so that each faction would have their own continent and I've got tech research set to 10% so it is an extremely long game.  I suppose either of these, or maybe even the 100x200 size map, could have helped encourage the sort of issue that I'm having.

Thanks for any help that can be offered but I'm guessing I'll have to abandon my save unfortunately

AFAIK, its normal that aquifers wash away improvements.
Same for global warming, change of land tile elevation because of sealevel rises can cause improvements to disappear.

But condensers or boreholes directly removing improvements on tiles it affects (with drought or raininess) is a first.

In edit mode I tested adding a ton of farms with condensers on a map and adding aquifers all over the place an it never caused an issue.  If you do the same on the save game you'll see this happen and even that it sinks other bases around the map which are nowhere near where you are editing.  I never recalled having global warming doing anything except dropping some tiles into the sea.  All the rest were left unaffected, at least as far as tile modifications go.

The ingame editor isn't the game, you know...
And its also normal game behaviour that bases without the seadome building can sink and be removed from the map.

I'm just saying if you want to quickly test it then use the editor.  You can also test it by playing the game normally.

Yes, bases can sink due to global warming, but have you ever sunk a foreign base by drilling to aquifier a continent away from them?  It's quite something to see

As Geo said, in the editor it won't happen, but in the game it's all normal behavior despite seeming odd. And it gets weirder the bigger you make the map. I play on 360x180 maps all the time and you should see the chaos that goes on because of various terraforming and global warming.

Hmmm, odd.  I don't have issues like that within the game.  Must be an intermittent bug.  But it is good to know that it is the map size that causes it.  Guess I'll just go back to playing a supported map size.  It is just as well since I found out that the 2048 unit limit still exists so large map sizes are just not feasible for builders and can really on work for warriors.  Ah well.  Still a fun game
