It happened to me in a singleplayer world in two different trident killers. The first one was in a farm in the Nether, I finished my session in there and when I logged in the next day the trident was missing. It wasn't below the farm since that's the storage area, but if it fell more that that it would've ended up in lava.
The second time was in the Overworld in a farm 130 blocks from the ground, I logged out away from the farm and in the ground, but close to it so it was rendering. I logged back in and the trident was at ground level.
When I come into the area via elytra everything seems to be fine (I don't have Nether portals close by).
