Is it giving you any sort of error message?
Edit: I re-installed the game and the current version seems to be running fine on my end. Only thing I can possibly think of is the save data file being corrupted. Let me know if it gives you an error message and I may be able to help further.
Not sure what the issue is. I'm unable to replicate it. It could possibly be a corrupted save data file? You could try going to "C:/Users/[YOU]/AppData/Local/" and deleting the "BoofiesBunker" folder. Just keep in mind, if you had any previous save data, this will delete it. I'd back it up in a different location before trying this. Just in case it doesn't work.
