Tridents dissappearing

Since the new update I noticed my tridents had disappeared from my farms. Since player holding trident appearance changed I figured they reset. But after filling the farms again and leaving to work on another project after returning they were gone again. I have tried naming. Checked the hoppers, storage, and furnaces. They simply vanish. This is now the third time I have loaded my farms. It just continues to happen. Now matter how much problem solving I do. I believe it has something to do with the coding in the recent update. Thank you for your time.
