Came here to say that while Myrellion being blown is a nice plot twist/option, in my playthrough(literally 1 full weekend sitting) it didn't blow up instantly. I blew up pirate base(without even realising it is on Myrellion) and then carried on with stuff on Myrellion, then, before finishing half quests on it i switched to other places. I've defeated frost dragon, accidentally found out how to earn shit ton of money via towelling, so i came back to buy a spaceship to Myrellion. Planet was alive and well MONTH after nuclear shenanigans. But after i bought the ship and outfitted it, suddenly Myrellion had nuclear winter... Had the effects been instant or take less than a day, i would've realised my mistake before too late and would've fixed it. But now i am forced to either restart or go back to me buying ship, beating all the quests before purchase and then yeeting on the new ship, leaving everyone dead.
