PANIC: unprotected error in call to Lua API (table index is NaN)

[Angelo Locritani]

I'm playing with a modified revision 6195: it's r6195 of trunk + one of the latest version of translation branch, but I think that what happened is not related to translations.

I'm playing 3rd barbarian tutorial. The game was started with build16 and continued with trunk version.

During autosave, game crashed.

I'm attaching savegame and replay

Here what was on console:

Does the savegame load/play in b16?

  status incomplete

The savegame doesn't even appear in the list of loadable games.
An autosavegame_2 appears; I think it's the backup savegame, renamed "_2" while the new savegame is created.

I mean the savegame you've originally loaded. Does it play okay in build
16?

[Angelo Locritani (alocritani)]

I'll check.
Anyway, I want to signal that the problem doesn't happen on every savegame, but only sometimes.

Indeed, I was able to continue playing with several revision of trunk version (the HEAD revision at different times).
Maybe this screwed up something...

Anyway, I will check and let you know about the savegame I loaded in the beginning of last "game-session".

Loading the game in build16 produces the following error:

player info: unknown/unhandled version 14

Okay, something is really messed up. Thanks for the additional
information.

  status confirmed
  importance low

I've further details:
I found that the problem arises only after I start conquering the red player's buildings
I then played with the --nozip option. I'm now attaching the savegame's folder (zipped by myself), so maybe you can understand which data is wrong.
Loading that file causes a crash with the following error:

[...]
Registering script: (map,texts)
done!
 Game: Reading Map Data Complete done!
Game: Reading Player Economies Info ... terminate called after throwing an instance of 'File_error'
  what(): RealFSImpl::Load: problem with file/directory: /home/angelo/.widelands/save/TestCrashingGame.wgf/binary/player_economies

Indeed, the binary/player_economies file is missing...

Setting to incomplete for bug sweeping.

The lua persistence layer has been changed since this bug has been reported. This is likely fixed, but I cannot check nor reproprudce, so i am setting this to invalid.
