So. I had this mod for a while, removed it, started a new world. And I've noticed its messing up Serene Seasons tags. All Summer and autumn crops no longer have tags on them.

To be clear I no longer have the mod installed. I scrubbed the config aswell and have a new world loaded up. I'd really like to understand why this is happening, as it may be effecting games with the mod still installed also.

Ok, disregard. I made a datapack that gave these crops seasonal effects and didn't remember to remove it.

Solved.
