Hello, vlss. Thanks for feedback!
Mentioned by you, space mod placed restrictions in game so if stack size of rocket fuel is more than 10 game won't load save game and won't let you start new game while showing in-game message.
So I've made another mod that introduces to the game an alternative for rocket fuel that hopefully will mitigate some issues. Basically, mod adds another item which stack size isn't limited by that space mod. Two recipes will hopefully help you move big piles of rocket fuel more freely.
