hi, im trying to update my server's pixelmon from 2.8.0 to 2.8.3. however when i do so, no data is saved, and there actually isnt anything in the mod that works. ive checked the items in creative and they werent there. ive tried downloading each version to 2.8.3, but 2.8.1 wouldnt install itself, despite it leaving a checkmark on the mod page.
any solutions?
