You should delete the old version before updating. Sometimes I remove files or change their names. If the game loads these old files, it can cause instability.
Remember that the Steam Workshop version will tend to be more up to date.
I forgot to change the British NF tree to cost 70 days after testing it using 7 so if you were in the first ~10 people to download this, you will probably want to download it again.
Fixed now though. Sorry!
