Context after creating a Stat Block of type "Character Sheet (Pathfinder 1e). At the bottom, in "Tour Spellbook". When in Level 5, I add the ID 704055 (which references to a spell called "Teleport" ( https://www.worldanvil.com/block/704055 ), after saving, then, the saving option do not reappear anymore, whatever I do. I have created a brand new character, added piece by piece all information and saving them. It is exactly when adding this particular 704055 that the character is then stripped of all options like "save, delete, tags, world, folder, visibility". It is there fore not editable anymore.
Go to a context where you can create a new Stat Block. Create a Stat Block of type "Character Sheet (Pathfinder 1e)". Insert mandatody data (characteristics, race, ...), no importance of their value. Go to the bottom "Tour Spellbook". In the line "Level 5", add the ID 704055 Consequence: all the buttons on the right disappears forever ("save, delete, tags, world, folder, visibility") for this character. How to unblock: create a new character sheet, copy paste all vaues except 704055, save, delete the old blocked character from the stat blocks list.
After many tests, I found the cause : it is the presence of the "table" bloc inside the spell description. I reproduced the bug with a new spell : whenever I add a table, it blocks the character sheets. When I remove the table bloc from the spell, then the character sheet works well again. I duplicated the spell Teleport in the block 1350492, and it works. The problem is: if we do not have the control on the "bugged spell", there is no way to unblock the character sheet.
