Museum Completion major issue

So, long story short, I asked this question on the steam forums and got no help there. I donated all 95 items (and yes I counted three times and made sure everything is there before someone asks) and no achievement, no letter, no stardrop and gunther doesnt even acknowledge I finished the museum. Any help? I am currently playing 1.3 beta and I donated all the 3 dolls so that can't be the issue.

 

Are you playing in single or multi player?

 

Singleplayer

 

Can you zip your save folder and attach it to a reply here?

Can't zip it and upload to the forum? If on windows, right-click, send to, compressed folder. Your link wants a log in.

 

You're missing Obsidian. I donated that and the collection was complete, and I got the stardrop.

 

Holy shit you're a lifesaver!! I thought I had obsidian donated but I guess not. Thanks again!!

 

You may have at one point, but lost it when rearranging things? No problem
