A couple months ago I would trap 15 wooden boxes with the keys in them and put them in a bag. I would get them as needed with my other chars. I could open them and they wouldn't blow up. About a month ago I went to the bag and got a box and opened it and it blew up(the rest of the boxes in the bag were also armed now). Not a big deal was just wondering if anyone else noticed. Only thing I have to do different now is take the key out of the box before I make the trap. Maybe I was doing something wrong, who knows...
Yes, I'm talking about when you first make them with your tinker. I used to be able to just make them with the keys inside and put them right in a bag. Then I would grab them with other chars. I would open them take the key out and lock it then unlock. I did this for months. Then recently I went to the bag and got a box and opened it and it blew up. All of the boxes were armed. When I make them now with my tinker they are armed/set from the get go where as they used to be able to be opened(by any char) as long as you haven't used the key to lock and unlock it.
