unable to build rocket

[MachineGamer728]

after rebirthing with 415 dark matter i progressed through to intersteller travel, where i am now softlocked, as i can build the rocket needed to travel using the antimatter. It says it has already been built, and said that since i rebirthed. Im geussing a quick if statement should fix this up, but idk if the game is still being fixed. If not, lmk if i can tranfer my progress to the other version.
UPDATE: reloading the game seems to fix this if anyone else has the problem
