Farming UI disappeared

Hello,

I've just noticed, that I can't enter the 'place mode' upon using a fence, since the activate button vanished. There is no possibility to place crops at all. Prunning, harvesting, breeding and other stuffs like crop display is working though. I've got no clue how to fix this. I already restarted the game, swapped servers, chars, deleted game cache, reseted the whole game UI without any success. Please let me know what I can do to get it functional again. Thanks

 

realized, that none of my alts reached farming master yet so that's why they can't use the old moon fences. This is an actual facepalm
