So I upgraded a whole bunch of mods and then got the following errors:
System.Exception: Error loading mod: Confederate ---> Halfling.ObjectText.OTNavigateException: Unable to find node at path "<./Data/Effects/particles.txt>
System.Exception: Error loading mod: Cosmoteer Plus ---> Halfling.ObjectText.OTNavigateException: Unable to find node at path "<Ships/ai.txt>/BountyBrain".
System.Exception: Error loading mod: Additional Weapons ---> Halfling.ObjectText.OTParseException: Group at path '<C:\Program Files\Cosmoteer\Data\rules.txt>' already contains a node named 'PARTICLES'.
System.Exception: Part ID 'laser_point_defense_celly' must be in the form of 'author_name.part_name'.
Not all of them at once as I turned one mod off after every time I got an error, though I stopped after the several errors.
