Every time that I try to edit my private homebrew it doesn't save and I don't know what to do, I've tried restarting my computer, I'e tried using another computer, an I've tried using it in a different window, but nothing is working and I'm getting pretty mad.

Hello Rzargo, could you please walk us step-by-step through the actions you're taking while editing your homebrew?

Are you clicking the save button?

Yes

I doesn't happen often with my other two homebrews but it happens every time I try to edit one of them.  1. I pull up D&D Beyond, 2. I go to "Creations", 3. I go to "MY HOMEBREW CREATIONS", 4. I click on the homebrew tab that I'm talking about, 5. I click "EDIT" and edit the things I want to edit, 6. I click save, 7. I repeat steps 1 through 3 to check if it saved.

I made a new homebrew to test it out and I can't change top section like the flavor text and such, but on other homebrew and the new one that I made I can edit the bottom area the traits, proficiencies, ect

Thank you for the information, Rzargo!

So if I'm understanding correctly you're modifying the description fields in the main part of the background, and when you choose save the changes aren't saving? And this is only occurring on one piece of homebrew?

If that doesn't sound quite right, please correct me. 

Would you be able to link your affected homebrew, please? I can take a closer look from there. :)

make sure you're clicking save before you click any '+' sign as I don't believe you can edit multiple sections at once.

to test, simplify your #6 step...instead of 'things', edit one character and then save...then try that again in another section.   narrow the variables until you have one exact edit that's not saving.

It's not my only homebrew that it's affecting because I've figured out that In the initial making of the description fields it saves but after that I can't edit it anymore on any of my homebrew.
