i tend to find myself doing simalar things,
feeling sure I had missed an item, that may become important,
such feelings are very agitating when you end up serching and re-searching every area for such treasures,
even more annoying when you realise later in the game that their WAS something you missed, despite your efforts.
In burmecia particulary I find myself, knowing that its a fake treasure chest, just HAVING to make sure, such things resulting in my annoyance when i realise that I was right, And It was fake
but anyway, the constant '!' mess with my head, for about ann hour after everything in site has an '!' over the tope.....its at this point when I realise I needa break from it.
