minor improvements that reduce the scope of these bugs, but we will not
be able to completely fix them.
Clipping problems
Clipping problems [FS#119]
In some cases sprites are not drawn as one would expect. Examples of
this are aircraft that might be hidden below the runway or trees that
in some cases are rendered over vehicles.

Duplicate (station) names after renaming
Lost trains ignore (block) exit signals [FS#1473]
If trains are lost they ignore block exit signals, blocking junctions
with presignals. This is caused because the path finders cannot tell
where the train needs to go. As such a random direction is chosen at
each junction. This causes the trains to occasionally to make choices
that are unwanted from a player's point of view.
This will not be fixed because lost trains are in almost all cases a
network problem, e.g. a train can never reach a specific place. This
makes the impact of fixing the bug enormously small against the
amount of work needed to write a system that prevents the lost trains
from taking the wrong direction.
Forbid 90 degree turns does not work for crossing PBS paths [FS#2737]
When you run a train through itself on a X junction with PBS turned on
the train will not obey the 'forbid 90 degree turns' setting. This is
due to the fact that we can not be sure that the setting was turned
off when the track was reserved, which means that we assume it was
turned on and that the setting does not hold at the time. We made it
this way to allow one to change the setting in-game, but it breaks
slightly when you are running your train through itself. Running a
train through means that your network is broken and is thus a user
error which OpenTTD tries to graciously handle.
Fixing this bug means that we need to record whether this particular
setting was turned on or off at the time the reservation was made. This
means adding quite a bit of data to the savegame for solving an issue
that is basically an user error. We think it is not worth the effort.
Duplicate (station) names after renaming [FS#3204]
After renaming stations one can create duplicate station names. This
is done giving a station the same custom name as another station with
an automatically generated name.
