Thank you for that list: that is most helpful, both for players on the server and for development works. DO you think that you could perhaps number the list to make it easier to refer to it?
In respect of some of the issues that are bugs in the code that are not yet solved, it may be difficult to reproduce, and therefore fix, these without either a deterministic set of steps to reproduce or a relatively simple saved game in which the problem occurs at a deterministic time and place that can easily be found. If you or anyone else is able to produce such, that would be extremely helpful.
One issue is not strictly a bug, which is the player colour set. This is the same as Standard; I wonder whether some revision should be suggested to Standard, which could then be backported into Experimental when implemented?
The train placement after game loading issue I think derives from Standard, as I remember this issue in Standard games long ago (I think). I have certainly not changed in Experimental the loading/saving mechanism for convoys. Are you aware of whether an issue like this has been fixed in Standard in the last 2-3 years or so?
As to aircraft on a runway, the mechanism here is the same as Standard, except, in Standard, runways are allowed to be very short indeed. However, I am not sure whether this is undesirable, as I think that it represents a real life parameter, which is that aircraft will only take off into the wind. In Simutrans, there is a simulated (but fixed) wind direction, and aircraft will always take off and land in that direction. Changing it to allow them to take off or land in any direction would make the game less realistic. There are remnants of code that suggest that a variable wind direction was once attempted but abandoned many years ago. Simulation of variable wind direction was also suggested a while ago by The Hood in the context of sailing ships, but was not taken up partly owing to the complexity of coding such a thing and partly because of how difficult that it would be for players both to understand and to plan for changing wind direction. The same may well apply to aircraft.
The electrification of bridge ramps (the issue is not just confined to one type of electrification) should be fixed with the next release, as this issue is now fixed in the code.
I think that I have fixed the power network desyncs (in that I can no longer reproduce them on a simple setup), but this has not been tested rigorously.
Any assistance that you or anyone else might be able to offer in narrowing down and/or fixing the bugs reported here would be much appreciated. Thank you again for your help.
