I have made no mods (for this game) so you can tell me if I`m wrong but it seems there is no way to update your mods. I say this because every mod I`ve seen only has 1 change note and I`ve seen modders reupload their old mod to update it. I think that being able to update your mods is a major thing at least for me. I currently mod for four games and have plans to spread out to other games like this one but not being able to update a mod/level is a big down side for me since I enjoy doing those little bug fixes or adding another level in after some time as a pleasent supprise.
