old save

I tried to search and was unsuccessful looking - trying to see if your mushroom cave would have a dehydrator if you have a save file that already had the cave. I did not get one and was unsure if it was a bug or it only spawned on creation.

I bought SV Saves and then I can’t run the old save game

I went down the list of possible fixes like verifying integrity files, uninstalling and reinstalling the game, and restarting my computer. It's only my old saved file that keeps crashing, any other game file I made recently load perfectly fine. Error Log: Message: Error loading...

In an old save, I don't have a secret notes tab in my collections menu, nor have they been dropping in the world. Is there any way to update to add them in? I have features from 1.4 and 1.5, but not this one. Thanks!
