This isn't too serious.
When my trawl net detached after being full I looked through its contents and found one slot was empty but colored green, as if there was a perishable item there. When I clicked on the green slot it came out as an empty slot.
I'm not sure if it applies specific seasons, sections of the ocean, or both, but it happened during hurricane season on medium/ deep oceans.
