Subject: [PATCH] Issue where index is -1 or more than total

When the user does a crazy amount of swapping the component get diff as negative or positive and sometimes result in an overflow 'or' underflow of the index results in the component sort of not responding. This only reset the value to 0 or total if the loop is false
