Hi,
Currently (v.3.63) on Windows
a) Launching the game (from desktop), then loading a savegame results in loss of player's previously active zoom level setting (i.e.: game starts with default zoom level of maximum zoom in).
b) If savegame was played for a bit, then player backs out to main menu, and finally re-loads a savegame at that point zoom level is retained.
Based on the above, it appears zoom level setting is stored in memory but not written to disk.
I acknowledge this is a small QoL thing and not urgent in anyway. Having said that, I think it would be a small improvement if zoom level is stored on disk and retained every time.
Thanks
