Hey soI don't know what you've tried thus far but it sounds like a shader error to me which is the cause of most hang ups at 100%. Are you playing on a PC? Do you know how to delete your shader cache?
If you're on a PC:
Documents\My Games\FarmingSimulator25\shader_cache <-----delete the entire folder
Documents\My Games\FarmingSimulator25\jim_cache <----- Delete the entire folder
Restart the game and see if it loads. If not:
Remove all of your mods except for EasyDev and restart.
Also- if it's hanging at 100%, your log will tell you why.
