with your latest push 'reverse', 'mirror' and 'alternating' flags for reversing schedules are not saved. They can be restored from an old savegame however.
[edit] the actual process of saving the game, already resets those flags.
Sdog,
this is because, if it was set to save them, it would require incrementing the version number, which would then make saved games incompatible with existing versions. Don't worry - it won't be released in this state, but this is sometimes necessary for the -devel branch.
