"Could not find event."

I found the fix. You need to enable the mod in the launcher. I hadn't done that.

unsure if its a bug but i'm having an issue after it wont load up the the attention screen but unable to access the main menu i am using the core mod.

I believe it's because the cheat menu hasn't detected the core yet. Once you wait a month, it should work as normal.

I have 'Tranxalive's Mods Core' installed and active, but no matter what I do or how much time I wait, I can't use your Cheat Menu. I have placed Tranxalive's Mods Core to load before AND after the Cheat Menu mod, but even after waiting for 5 months in-game on both occasions, I can't access it. Could I receive any assistance? I really liked the way you made your mod.

Probably Stellaris overwriting the event, or another mod. I'm surprised it took it this long. I use flags to enable the options and stuff. The idea was that it was supposed to be a form of copy protection, but I've pretty much abandoned my stuff, so it's effectively fair game to dissect my mod. I would appreciate credit to be given, but again, it's fair game.

Anyways, just type into the console (or copy and paste):

" effect set_global_flag = core_installed " then
" effect set_country_flag = core_installed " then
" effect set_global_flag = cheat_menu_active " then
" effect set_country_flag = cheat_menu_active ".

That should enable it for the rest of the game. If it's not working for any new games either, you'll have to type that in.

Stellaris doesn't allow multiple commands in the console, for some reason. I thought it did... But according to a thread on Reddit, it's possible to make a text file in the Stellaris folder in your Documents folder, past Paradox Interactive.

I think the file should look something like this: (Also, ignore the quotation marks.)
"

effect set_global_flag = core_installed

effect set_country_flag = core_installed

effect set_global_flag = cheat_menu_active

effect set_country_flag = cheat_menu_active

"
Then type into the console:
run *name_of_text_file_here*.txt , and it should work fine and quickly.

Honestly, now I'm kind of annoyed at all the flags, so I might update it later. Probably not though.

It's working perfectly now. Thanks for the tips and the fast reply!
