Using the OGL 5e character sheet. The Wiki says the following: "If your character is multi-classed, when rolling your hit dice, a pop-up will ask which of your character's current class's hit dice you want to roll. The total and current hit dice fields are just text fields, so you can use them to track totals for any number of multi-class configurations. Say, if your character is a Fighter/Cleric you can put "F 2 | C 1" in the field to track that you have 2 Fighter and 1 Cleric hit dice available." This is not correct. The current HD field is not a text field, it is a numeral counter. It does not allow the use of letters, and if you attempt to use special characters, the field is deleted when you close the sheet. Is this a feature or a glitch?
