Hi folks. I've got some multiplayer issues with crab pots that I've now seen across 2 different files, so it's time to report.
As a non-host, when someone else has taken the fish/trash from the crab pot and loaded it with bait, it shows me a crab pot with black inside (aka ready to harvest), and still allows me to try to place bait in the pots. I get the interaction where I attempt to harvest from them, but pull up nothing, and then still only get one normal result the next morning (from the other person's bait). This does not look like the usual light red empty crab pot, or dark red bait-inside crab pot; instead, its black on the inside, ready to harvest. It's not just sprites--I was able to do the pull/harvest animation for these "black" already harvested and baited crab pots, and the pictures below show what the game decided to use as a sprite for what I was harvesting. (I did not get any extra milk or stone or pots from this; these were what I had last scrolled over in my inventory when I took the images, and it's why there are a bunch of images to show the sequence.) In addition, when I fill a crab pot with bait, then enter a building (house, greenhouse, etc) and then come back out, crab pots look filled with black/ready to harvest and seem to have no bait in them visually. I did not test to see if buildings would allow me to attempt a second false harvest. I had this bug occur on pots placed on the 4-corners farm on a 2-player file, and on crab pots placed in the ocean on an 8-player file.

I've numbered the images 01-09 so you can see the progression. 01-06 and 07-09 are on different days, same 2-player file. (I can attach the full files if needed. Images are from 4 corners/2 player farm.)
