Corrupting saved games

[GPS51]

Hello again, I keep having my savegame files corrupt. >< I was wondering if someone could tell me what to do to A fix/debug them or B how to keep that from happening. Here is the console readout. Sorry it's so long. I did see where it said the ufo_craft_fighter wasn't linked to any mission. Each of the saved games that corrupts has to do with an alien mission that is unlinked. I believe another had to do with the alien base mission being unlinked. Thanks

My friend,
Do you suffer from the heartbreak of... undead ufos?

Error: UFO 'craft_ufo_fighter' is not linked to any mission
2010/02/20 13:52:11 ...subsystem 'aircraft' returned false - savegame could not be loaded

... why yes, it seems that you are. Plan 9 has struck again.

Seriously. Your game session acquired a zombie ufo and at that point the game became unsavable... as savegames with zombies can't be loaded.

More on the threat posed by undead alien spaceships can be found here:

Ah I noticed the other thread but didn't connect the two    Sigh...tis a sad day along with my share of no free inventories CTD

I'm fairly confident that the bug is actually widespread but unreported because it is almost asymptomatic. It does not cause an immediate crash and a ufo shootdown is reported on the scroll. In the midst of a late-game multiple ufo dogfight spread over several bases who's going to notice one ufo flying away unscathed? I didn't for a very long time. And when the ufo is not near a radar tower it's a case of out of sight, out of mind.

The only overt symptom is when the savegames stop loading and that can easily be attributed to almost anything... including the latest svn update.

And so the actual bug goes unreported.

Clever Plan 9 is clever...

This was a bug between r28510-r28627.
To "fix" your save you should load your save (which is only possible with versions < r28550) with a DEBUG build and type the following commands into the game console:

Code: [Select]

debug_delmissions
debug_destroyufos
This will remove all the UFOs and missions, resave then update to r28627 or later to prevent it happen again.

Code: [Select]

debug_destroyufos
This will remove all the UFOs....

Does this destroy all ufos currently in the geoscape simultaneously?

[zapkitty]

Does this destroy all ufos currently in the geoscape simultaneously?

The reason that I asked is that it doesn't... and I've lucked into a savegame configuration that seems to always generate a zombie if you use debug_destroyufos shortly after the mission starts to prove it 

Also, not only does this "Plan 9" bug seem to account for savegames that won't load, it also seems related to savegames that will load but crash  to the desktop when you start the clock.

I'm composing the report and will post it and the savegames in the other plan 9 thread...

... also will describe other strange effects...

Brilliant alien plan #9 is brilliant...

geever, add check for link between UFO and missions into saving code.
