After some troubleshooting and testing with different designs, I've found why on occasions a character may not save. It relates to the markings design and if it's blank or not. If starting with a new character, a random template is chosen. If the tamplate is either the canine, rodent, or dragon. If the user decides that they do not want a design and choose blank, than the character will not save at all. However, if just changing to a different design, it will succeed. This also applies to loading a saved character, if the character has design markings and it is changed to blank, the character will not be saved. That's all. I'll look into a solution around this until an update fixes it.
