TRS 2019 SP4 introduced a regression in Surveyor behavior related to environment settings on saving route. It would be good to fix this regression in SP5 - I'm not able to find any information about fixing it, therefore I'm posting it here.
Reproduction instructions
Prerequisite: the local date on your PC should be set to some autumn/winter days (e.g. October or December)
1. Create a route, go to "Edit environment" > "Location" and set the starting date for e.g. July 15
2. Put a couple of "Tree Sourwood 01" trees on the route - they are available as a part of the core game, and they are seasonal, so they nicely show what happens.
3. Save the route, do not save the session
Expected result:
* Tree should remain green, as the environment location does not change
* Configured date/time in "Edit environment" > "Location" does not change
Actual results:
* Tree loses all leaves and switches to winter mode (actually, all seasonal assets are affected)
* Configured date/time in "Edit environment" > "Location" remains unchanged
To reset the view, one needs to go to "Edit environment" > "Location", change the day to July 14, and then back to July 15.
