Hello SnipersHunter.
There were users with similiar problem. I think a complete reinstall of the game could help. Uninstall the game. Delete all savegames and leftover. Restart the computer. Install the game. Patch to 1.2. Make a backup copy of the whole folder. Extract a fresh copy of JSGME to the game folder. Copy the mods to the new MODS folder. Activate the mods. Switch Uplay to ever start in offline mode.
