And I found a more effective simplification for legw_planet_uninhabitable: just check for colonizable_planet = no and you'll never have to change this trigger again.

wow ... thats nice and simple, i guess i will try this change in the next version.

my code is sure not optimized, as i started this project years ago, where i even think colonizable_planet routine wasnt even in the game. also i had 0.0 experience coding anything when i started, meanwhile i got up 0.5 but well ... things are doing its job atm.

i also dont know if colonizable_planet is giving correct values for add-on based modded planets, planets that become habitable/inhabitable through events in the game or just knows the game base planets.

anyway, much thanks :)

Yeah, some of the code improvements here are quite recent. I'm glad to help! :)
