i have had it happen 2 times already and i am very sure that the oxyfern was not picked up by a pip.
i have tried to reproduce my scenario in the steps below.
Steps to Reproduce
reproduction: 1. oxyfern seed is provided by printer 2. dupe brings oxyfern seed to storage bin (prio 9, only oxyfern seed, adjacent to pneumatic door, several pips in same area as storage container, transfering dupe is on the other side of the door) 3. oxyfern seed is still listed in the material list, when i click it, the compactor is selected, the content is empty though 4. an oxyfern image remains on the other side of the door (maybe just an unrelated visual glitch) 5. when i change the storage compactor settings or destroy it, the oxyfern count is decreased 6. no oxyfern is planted by the pips
