[Dennis A T (dennisat)]

I have had a similar crash twice. Both times a menu appeared inviting me to look at the Activity Summary. However, the crash prevented me actually selecting anything on this menu. On both occasions I was attempting to move the train after I had received the activity completion message. I've been unable to re-create the crash at will even using the same activity in the same circumstances. If it happens again I'll make more of an attempt to grab any debug data.

Is this Activity Summary a feature not yet fully implemented?

[Cédric GNIEWEK (sharpeserana)]

Does the problem still happen with version 1.4?
