I'm not entirely sure this belongs here - it's not really a bug, so much, but more so than anything else.
I have SimuTrans installed via Steam and today it (automatically, on start) updated from 120.1.1 to 120.1.3. This is reflected in the main-menu dialogue ("This is Simutrans: Version 120.1.3 Feb 2 2016") but the initial loading screen (immediately following packset selection) still displays "Pak 128.Britain 1.17 Simutrans 120.1.1". Not sure if this is to do with the packset or with the main SimuTrans application.
As I said, not really a bug, but caused me minor confusion for a second.
