Hey, even though you didn't know what IMSM "100.0.2" was. I googled it and realized that the server computer had two mods loaded and the other computer only had one of them. I didn't realize the second computer needed all mods to work. So other players joining a server with mods must have the exact same ones as the server. Thanks for your time! As well this is my first forum post, I am not sure how to end this post and state that the issue was solved. Thanks again!
