It looks like you're playing the version hosted on philome.la. That was the original site where Seedship was hosted, but the site was discontinued and became read-only in 2019, so I can no longer update the version of the game there and it's forever stuck on version 1.3.1.
I fixed this bug (and a few other minor bugs) in version 1.3.3, so the itch.io version and the mobile app versions don't contain it.
