Museum glitch, can't get the "A Complete Collection" Achievement

[SpringCycle]

Hey y'all. IDK if this only occurred since the 1.6 update but I can't seem to get the "A Complete Collection" achievement and even if I've given all the needed minerals and artifacts to Gunther (yes I've checked the collection tab when i check my inventory all of them) and he still gives me the line that I don't have anything to give him and asks me to go treasure hunting. Genuinely don't know what to do so I'm desperate for any options!

If I am missing any treasure that's not on the collection tab please let me know!

I've checked it wt or w/o mods and the results are the same :( I need help y'all!

When you check your collection it shows what you have found, not what you have donated. Is there an empty space left in the museum maybe?

Prismatic shard? I played for hours before I figured out I've had what I needed the whole time

I had a similar situation a while ago, for me the culprit was one of those weird dolls, I had found it but hadn't turned it in, and since their description is always "????" I didn't notice it for way too long.
