Thanks for the feedback! I'll try to figure out the bugs. Maybe there are some additional details about how the errors occurred?
Not too sure? The dupliacte candle happend when I had the hat in my inventory and lit the candle. As soon as I picked up the candle, it was placed in the position of the hat and showed as 2 candles. The one I used and the other was just there. There was also still some space in the inventory. For the bullet I tried loading all available bullets at different amounts, but always seemed the last bullet was not loadable. Wish I could give you some more info. Just to add on, I am using Chrome browser.
