I left the Census Office and went over to Arrille's Tradehouse. This was my very first time in the game. I see a nice-looking spear leaning against the wall and I think to myself, "That looks nice. I think I'll buy it," and so I click on it.
Before I know what's going on everybody in the building is rushing around counters and down stairs with weapons drawn. A box appears on my screen asking me if I want to load a previous save.
Been there. More often then not you can't tell if something is owned if it's outside, or inside half the time.
Kinda wish they added a put-back-to-default feature, where the shopkeeper runs up to you and says 'HEY PUT THAT BACK!' and you can click 'Ok' to do it. and it undoes the action and everyone's happy, , or click 'No Way' and keep it with angry mobs around you. Could fix a lot of problems.
A second option they could have done, is if your a shop and items owned by a shop-keeper, they don't attack you, and you can go to the counter and it's pre-selected for buying (maybe have an eerie green glow spell put on you that lasts an hour till dispelled, and you can't hide/go invisible with it on. Like a big Neon sign pointing to you that says 'I stole Stuff, Arrest me please!'), so If you leave without paying the guards know and you are immediately captured/arrested. But that's wishful thinking.
