* Revert breakdown_chance to (mostly) its original behaviour.
* Create a new breakdown_chance_factor to hold breakdown_chance
from improved breakdowns logic.
* Revert airport crash probabilities back to original behaviour, with
modified behaviour only during emergency landings.
* Low power breakdowns now only reduce the power of the engine which
has broken down.
* Low power breakdowns no longer reduce speed directly.
* Add callback function to run whenever improved breakdowns setting
is changed. Reset breakdown_chance_factor where required.
* More whitespace/formatting...
The train will reverse when its tail is within the waypoint tile.
This is useful for reversing on train en-route, without creating
dedicated reversing sidings or platforms.
This is because AfterLoadVehicles may indirectly check airport
properties via the NewGRF code.
Defer missing GRF error message output until the end of AfterLoadGame
to avoid obscuring any earlier errors.
These correspond to versions from v2.1.108 and v2.1.147.
The oil rig airport type bug is fixed as of version 221.
The oil rig type has been moved, but this is not a problem as
the afterload code already remaps it to the correct value.
The cost scaling issue also seems to have been mostly fixed
as of version 221.
Huge airports are not supported.
Annoyingly SpringPP has a bug where it uses the same ID for
AT_INTERCONTINENTAL2 and AT_OILRIG.
Consequently any aircraft approaching an oil rig in an SPP game
will be using the wrong aircraft movement data, and this will go
badly wrong as soon as the game is unpaused.
SpringPP divides all prices by the difficulty factor, effectively making
things about 8 times cheaper. Adjust the inflation factor to compensate
for this, as otherwise the game is unplayable on load if inflation has
been running for a while. To avoid making things too cheap, clamp the
price inflation factor to no lower than the payment inflation factor.
Savegame version 220
Bin all extra settings added in SpringPP.
Bin extra features: trip histories, more conditional orders/jump counter,
prev order time, snow-line chunk, town auto adv. campaign, etc.
Fix vehicle flags.
Fix bridges wrt height changes.
Handle 60-bit RIFF chunk sizes.
Doesn't deal with huge airports, loading games with these may
lead to undefined ehaviour.
PAX signals and traffic lights are ignored.
This is a port of the tracerestrict/routing restrictions feature
from TTDPatch.
At present this implements if tests (train length only),
and pathfinder deny and penalty actions.
This requires the use of YAPF. Note that restrictions are only evaluated
within the YAPF lookahead distance.
