OFFICIAL Missing-Crops, Trees, Buildings, Other Items

[Twigs]

I layered (water and trees) one farm (after extending) the same as the rest of the farm. The layering on the new bit seems corrupted. Some bits appeared empty, others partially planted. I took some trees off then tried to fill in the gaps. This was partially successful. I then left it alone for a few days, extended it again. Now the corruption is on the new area as well when I tried putting water on it. I obviously can't delete the empty plots, so what else can I do. I've cleared the browsers cache, reloaded the game a few times, but I still cannot put water on a lot of the new plots. Farm in question is nr 27.
