Weapons cannot be selected in Trader Joe and disappear in the game

Originally posted by James: It sounds like you may have game files left over from older versions.

For future reference, you have to start with a fully clean game between each major update. This means doing more than just reinstalling the game thru steam.

May* need to start with a fully clean game between each major update. I at least never had to. But there are some people who do, and in general it's just recommended to as a preventative measure.

Sometimes it works, sometimes it doesn't... When in doubt, full refresh.

If James' suggestion of clearing the registry doesn't do it, follow this, which basically includes removing the game itself and all other files such as those in app data on top of clearing the registry:

If you do the above, take care to retain your worlds/saves folders if you care to.
