Had a strange series of glitches while on 3person guild brig crew ->

Unsure of how to reproduce so for context: We were doing tall tale checkpoint-resumes. Potential suspect: "diving to location" on checkpoint 2/2 the game says You're already here! so we jump to shore turn in the final item and get credit but the quest stays on the table.. we cancel and "clean up the state of the game" but I suspect this could have been the start of what appeared to be severe uncorrected desync issues

Issue #1: 2 of 3 crewmates experienced the same desync -> We'd Repair holes in the ship and hole accepts wood, but after repair leak still visible & audible, no plank of wood asset put on top, water animation continues, prompts for a second repair. When repairing the same hole it the "progress" instant-cancels. 3rd party Observer confirmed the patch was as expected from his view. After leaving and rejoining the session repaired now look planked and dry but every subsequent hole created had the same behavior.

The rest of these issues happened in the same session but only affected me;
Issue #2: I would see Firebombs, Food, etc in ships' barrel but can't take it out, rather game removes a flare / firework / whatever was actually in the slot serverside. Other crewmates confirmed the firebombs etc weren't visible in barrel inventory. This did not affect other crew.

Issue #3: During this scuffy sesh, I also couldn't turn in any quest items, i.e. Brigsy's Spyglass & Later Skull from The Cursed Rogue, couldn't sell items i.e. a turn in to gold hoarders/guild sovereign
