Hi I have been updating the NPC in question on the new 5E sheet to include his spells in the new spell section. When I went into the NPC edit box to add his spellcaster level all of the stats changed to those of an Adult Green Dragon! Can anyone help? is this a known bug and is there anyway to revert to the original stats? This was a unique NPC I created so if not I am going to have to start again, so any help appreciated. Many thanks :)
