Sorry, but I haven't played in almost 2 months and I don't have the time right now. But whoever wants is free to take the files and modify them to adapt them to the current version and publish it.

I'm also seeing the crash that rotrules1234 pointed out. Can't wait for a fix so we can use this

I think your mod crashes the game. Here's the possible cause:

Unhandled exception C0000094 (EXCEPTION_INT_DIVIDE_BY_ZERO) at address 0x00007FF6781C5D45

Such crash doesn't happen if I turn off the mod.

Can you create a mod where non-gestalt empires are able to create planets like "machine worlds" or "hive worlds" ?

I am not sure and right now I am not playing the game. In any case, I will make a general update of all my mods to improve them and upload new ones when version 2.6 is released.

does this mod have decision "Restore Ecumenopolis" on Relic worlds?

I just checked, it works fine. It must be a conflict with other mods. Try turning off everyone else or use this mod manager to see where the conflict is - https://github.com/WojciechKrysiak/SCModManager

I can't build the arcologies district on the machine-forge world. Only the default ones (minerals, energy, food). I have no other mod changing the planet districts.
