I may be a little late to the party on this but as the title says it's nice now that we have the option for the month in Timetable mode to be able to see that trees in Winter (on the routes I have tested) have no leaves, not a huge detail but does add to the immersion factor now.
Actually to add to this during my experimentation I have found that sometimes there are leaves on the trees when its snowing then there are no leaves at other times, I just find it baffling, also can someone advise what the 'wetness' setting does in winter months? I have never really played much with the winter settings as prior to the last update the trees always had full leaves no matter what was happening weather wise so the only difference other than temp was the sun position.
Not all tree types lose their leaves during winter, and each winter month is slightly different in terms of how many leaves there are on the trees.
Thanks for the response that’s an interesting point and I get that some trees are also evergreen etc, however what I don’t get is for instance (just as an example) if I set IOW route to Dec and then also make it snow all the trees appear to have leaves but if I set it to Dec with no rain/snow the leaves are gone again, weird!
