every time i go to edit my character to level them up its making me rebuild the character from scratch this is incredibly annoying
This has been reported and posted here several times. It is a bug they are working on. I have found that if you make any changes to the character, reload/refresh your browser tab for demiplane before moving on to the character sheet or the next step.
A fix was just released that should address the trouble of changes to your sheet not saving. If the problem continues however please try signing out and then back in, clear your cache and cookies, and if it’s still happening after that don’t hesitate to let me know.
