UO Second Age

I find an unlocked boat, kill a poor hidden player, take key, clear the boat.
When I try to drydock it says "cant drydock with being on board".
Search the boat for hidden players and think its just his ghost on board.
Kill a char of mine to scout for the ghost. No ghost can be seen.
Toggle to war mode and back and still see nothing. Why cant I see his ghost??
This has to be some kind of weird bug.

sure there wasnt another hidden character aboard...or was it totally empty of all items?

Oh yeah I am sure, spent an hour going over it.

was it the right boat key?
actually I noticed alot of phantom beings lately.
Guardian Knight gated a nightmare I found for him and a phantom of it remained.
I had two phantom mounts in two of my houses after they were removed from an area.
You may had to either resync client or relog.

was the right key because I could recall off of it.

This is strange. Please page from the location if this still persists, or page if it happens again.

I paged when it happened but no one was on. I will page again If The issue is duplicated.
