Did you activate Mod Manager? Did you set crisis spawn years in the mod manager? Do you use other crisis managers than ACE?

It is impossible for ACE to spawn crisis at the year 0 of end game, so you must have set up something wrong.

open console command window and execute:
event acemod_menu.1

Select Crisis Manager -> Debugging tools - > open all windows and share screenshot of them. It should look something like this: https://cdn.discordapp.com/attachments/782374938442465281/807704518066176050/unknown.png

Or share the save.

Wow, you replied fast.

So, I could not figure out how to post Screenshots.I though that if I left the years by default, it would probably spawn the crisis at the default date (which was at 2250).

Regardless. I went through your other threads and noticed however that there was a way to force it to spawn so I used the ''event crisis.10'' and the Prethoryn showed up, but they are still not expanding and I am using the same mod without any other tool.

Did I do something wrong? I had the initial menu and accessed the commands through the recommended console settings and see that everything is ''active''. I wonder what else I can do at this point :(

EDIT: Never mind, even if the crisis did not expand but after looking at the situation log and they are devouring a crazy amount of ships (they are at 1K+) . They simple spawned between two awakened empires Lol

If you activated Crisis Manager but left its options untouched it will do nothing. BASE (default) settings mean the game will spawn crisis like in vanilla, not using Crisis Manager at all.

That said, glad it worked for you in the end. :)
