I saw that some months ago there was a similar problem as I discovered today on Order.
When I try to use any menues for my plot there is nothing shown in the lists.
Neither which structures already are built, nore those that are placed and waiting to be built. When clicking on a structure, I get no lists allowing me to construct something. Yesterday everything was still fine.

Please tell me that I do not have to wait until next Tuesday for being this fixed.
Building the plot is the main occupation of my craft-gnome and this week I would have a little bit more time than usual and the little one would be very sad if he had to be jobless for a whole week.
