Follow-up Comment #6, bug #19904 (project freeciv):

Friend of mine reports new developments with "ghost" unit in his boat. The
unit in question was unloaded to shore, but appears also as loaded to his
ship.

For one we know that his is not client side problem (only) as the situation
remains over logout/login cycle.

Now the unit on shore was killed - but it still exist in his ship, taking
transport capacity.

Follow-up Comment #4, bug #19904 (project freeciv):

So, server side nowadays stores unit's transporter as pointer, but client
still uses separate transporter id field! I wonder how well common code
copes.

Attached is added sanity checking for server side (but I'm quite sure this is
client side problem)

Follow-up Comment #3, bug #19904 (project freeciv):

I've seen this quite regularly, but not reproducible cases. It seems that unit
unloading method does not matter - I've seen it with units simply moving out
of boat, ships Shift+T unloading in cities, unloading at coast.

Maybe related thing is that in a coastal city where I were loading units to
ship there was more to load (from main map) than I anticipated. Once I opened
city screen to check the situation, it was revealed to me that I had loading
also those units that were supposed to be fortified to the city. I unloaded
those units one by one (via city screen present units -> menu). That went
fine. But as I were fortifying last one them, another one of the units got
unfortified. I fortified that, and again another (seemingly random) unit got
unfortified. I continued this a while, and found out that putting unit on
Sentry worked the same - random other unit lost its fortified or sentried
activity.
I then moved ship (with its single passanger (which was sentried all the time
- it never lost that status, by the way - not that I know when it had first
became sentried)) out of the city, and tried to fortify units remaining in the
city again. This time it worked just as it should.

I'd completely forgotten that one. Yes, could be. No wipe_unit() or goto
involved this time.

Likely to be related to bug #19612?

Details:

Recently I somehow got into a state where the client showed a unit as
(L)oaded, but there was no transport present; I'd previously loaded and
unloaded it from a transport, then moved the transport. Depending precisely
how I viewed the transport, it either thought it had the unit on board or
didn't. The unit could not be unloaded to clear this state.

Unfortunately it doesn't reproduce from a savegame, so this bug will have to
be a collector for other instances, but the attached screenshot should show
something is up (Diplomat loaded on... what?)

What I did was something like:
* Load a bunch of units including a Diplomat onto the Galleon, in a city.
* Changed my mind about the Diplomat and (tried to) unload it. (Possibly I did
something wrong/unusual at the point, I wasn't paying close attention.)
* Moved the Galleon out of the city.
* Started noticing weirdness in the client display.

It's possible this is a client-side issue (or that the server didn't send
enough info to the client).

This is S2_4 r21463 (experimental ruleset, Gtk2 client). I'm guessing it was
introduced by recursive-transports or the unit select dialog.
