Sadly seeds don't seem to correspond with any specific world, I've tried pasting the same seed multiple times and achieved many different results
Yes, it is very sad that some seeds don't work, but I'm afraid I don't have any way to fix this, I've lost the files for the game so can't make any changes... Which is so frustrating, because I know of a few other bugs I wish I could fix, and damn do I want to add and fix some dialogue... But I'm sorry, I won't be able to fix this bug or any others, I hope this doesn't ruin the game for anyone
