Risky Rain.2549

I have been playing for several months now, and I have consistently been unable to loot most plants. I can gather them to complete daily quests, but I can't actually pick them up when the loot box shows. The cursor becomes a white arrow instead of a hand, and also, pressing F does not work. Frustratingly, it is inconsistent. I can go to a potato patch and loot 2/10 plants. I don't understand why.
