To whom it may concern: Cause and fix for Gaia terraforming destroying features

[dezuman]

I haven't after a casual look found this already posted, so here:

The reason Gaia terraforming destroy features is because the three special 1-district gaia features all have zero weight, which apparently blocks terraforming swapping. Setting their weight to e.g. 0.01 will fix this.

Spoiler: DIY fix guide

If you want to fix it yourself:
Open up stellaris/common/deposits/01_planetary_deposits.txt,
go to the bottom of the file, and change this:

    drop_weight = {
        weight = 0 #does not occur naturally
        modifier = {
            factor = 0
            NOT = { is_planet_class = pc_gaia }
        }      
    }

To this:

    drop_weight = {
        weight = 0.01 #does not occur naturally
        modifier = {
            factor = 0
            NOT = { is_planet_class = pc_gaia }
        }      
    }

For the last three entries (d_buzzing_plains, d_mineral_striations and d_natural_farmland)

Will changing this fix pre-existing issues or require an restart.

If indeed it fixes the issue, it ought to fix it for all subsequent terraformations, but not ones already completed.

Probably won't help planets that have already been terraformed, since I suspect the features are irrevocably lost after the conversion. Should work for a game-in-progress before terraforming completion though.

There was a thread calling out this issue with a link to a mod fix a while back, but can't remember whether it was in the main or bug subforum.

Thanks for the tip!
The potential of these deposits already says "is_planet_class = pc_gaia". Why are you adding

           modifier = {
           factor = 0
            NOT = { is_planet_class = pc_gaia }
        }

to the drop weight?

Isn't it like that in the base game? I have no idea why I would have added it xD

Huh. I thought there were no 1-district gaia features in the code. Seems the intention was to make them never occur naturally and only as a terraforming feature.

That's the thing: Initially Gaia terraforming destroyed features because the 1-district features of normal planets had no Gaia-equivalent to swap to. In 2.2.3? they added these, but with 0 weight of occurring. This last point however also prevented them from being swapped to by terraforming, thus not fixing the issue it was supposed to.

Which means they implement a fix with out testing it...
