So basically me and my village partner have been in our town for a few hours; partner starts to build a Farmer house, i load the 12 nails into it. She chops wood for it, I get caught up in other stuff. Neither of us left town, so we are 100000% sure this is not player related. We look and poof, sign is gone, all 12 nails gone.
My partner claims this could be the "counter" for the sign-stomping method but truthfully we are baffled by this. 12 nails is a LOT of work for a bug to destroy!
Need some insight on this bullsht!
At the very least I am setting a warning out there, DO NOT leave valuable resources in building signs, start from worthless to priceless.
