Character sheet

While on the character sheet when you click on one of the tabs it jumps back to the previous tab. example: while on the "Core stats" and then click to "Class" it will change for a fraction of a second then jump back to "Core stats" but if you click on it again the second time it stays. After some time of being on the tab the same thing happens when clicking on another tab

This is usually as a result of a duplicate attribute called 'tab' or some such. Look for a duplicate and delete it and all should be right in the world again :)

Thanks, found them. I never touched anything in attributes, why/how would of been created 

They can sometimes be duplicated when there are multiple users in a sheet at the same time (the GM and a player usually), while vying for the sheets display setting there are certain mystical conditions that can be met that result in the duplicate entry. Sorry I can't narrow it down more than that but tab switching is at least a problem you only ever need solving once, after that you'll be able to fix it should it ever occur again (I've only ever had one instance in a solid year of playing). Happy rolling
