I agree: the server should remember which items and attributes he has
sent to the client. (Which IMO already have to be implemented in order
to make the item/upditem/delitem/delinv commands work right.) Using this
information, the server is able to issue correct upditem commands for
changed ground objects.

I think wasting bandwidth is ok if any other solution would be way too
complex to implement. But in this case I think such a "fix" would not be
the correct answer.

I somewhat disagree here: the bug is at least (slightly) confusing. For
example, go into Beginners and follow the instructions of the first
handle ("Type an A to open"). This applies the handle but the ground
view does not change until you move off and on.

I also agree here.

Map layer does not apply here since it is the ground view. But still:
the ground view holds only a maximum of 50 objects.
But this case is implicitly handled by the previously suggested
solution: the server would detect that the changed object has not been
sent to the client. Therefore it would not send any updates to the
client.
