Recommend first reading through the forums for other similar threads, or the bug reports (especially the sticky at the top to see if this is a known issue) before posting yet another thread. Often there are already good ideas posted in these places for what to do.
Also, recommend going into Ur and then coming back to your home. Sometimes that helps to reset things - I had a couple friends where this worked for them, and they didn't have to ask the devs for help - they were able to help themselves. If it doesn't work, file a help case or a bug report rather than posting in the forums. That will get to the devs much quicker and they will be able to help you sooner. Good luck!
I know it will be fine, but in the meantime, this means that those of us without our stuff can't do a dang thing to our houses because ALL our resources are gone. I couldn't even plant stuff in my garden because all my seeds and pigs are gone. All my machines are missing so I can't expand my house. I know they will get back to me eventually, but while others get to work, I get to twiddle my thumbs and wait around. Not fun.
I *could* be making wall sections or other needed things and selling them for profit...or a billion other things that glitchen with their stuff are doing, but instead, I'm economically disadvantaged, and that's not really fair.
I have plenty of herb seeds that I would be happy to give out to people to get their herb gardens restarted. Find me or IM me in game if you're in need. Crop seeds can be purchased or easily obtained from any pig. You can still gather the raw materials for making wall sections and there are Community Machine Rooms as well as Zany's generous offer. I understand that it sucks having to wait for your stuff, and I'm not trying to minimize the suckiness; I'm just trying to offer some ideas to ease the discomfort.
