The golden dice are supposed to be on top of the normal two starter dice, not replacing them. If you visit the cabin when you start with them, you seem to not be able to add normal starter dice which is a bug.
Yes, there is an interaction with fished up cargo & turts 😉 And yup, you can wish for a key.
Good finds on the infinite birds & fishing. I'll patch a fix for those later today (and some of the not so critical issues too)...
