The bed broke most likely because of driving the wagon
The other is the "zero'd out" bug - Its rare, but to those it affects, it affects them wholly. (i.e, no matter how many saves you make, it will always zero out on the first save/reload, unless someone manually edits them)
I can help you fix your save if you dm it to me on the discord
And/or I can dm you a fresh savefile that isn't afflicted with the issue, which should help alleviate the problem.
Usually, this works to workaround the issue, but I have heard of a couple times where it regressed to zero'd out.
