Re: [Rails-devel] Bug Report 1830 Rails1.7.2

[Stefan F. <ste...@we...>]

Mike:
thanks for the (detailed) bug reports.

I can confirm both bugs. Both are related to the fact the undo mechanism 
of Rails still has a few bugs remaining.

As going back in game history is based on the undo mechanism it shares
the issues.

This is one of the issues which will be addressed in Rails2.x and will 
be (hopefully) easier to identifier and fix.
As I focus on the core of the rails2.x now (and this is harder work or 
better more tedious work as I hoped it to be), I abstain from looking 
into the precise nature of the bugs (though I have some ideas where to 
start). Maybe Erik will have a look into it?

Usually the effects will not survive reload (as it replays the game from 
the beginning and thus does not use undo). So either the game is loaded 
in a correct state (most cases) or it is broken and unloadable (only a 
few cases). A general workaround would be a menu item that allows an 
automatic replay which simulates the sequence of a save and reload and 
will get the game back into a reasonable state automatically?
