[0.12.2][Twinsen]Crash when loading campaign 4 from 0.11.22

[kimsey0]

After upgrading from 0.11.22 to 0.12.2 on Windows 8.1 64-bit through the auto-updater, the game crashes when loading a save of campaign map 4 from 0.11.22.

The error message is:

Error while running the event handler: ...Data/Roaming/Factorio/temp/currently-playing/control.lua:347: attempt to index field 'attack_data' (a nil value)

This is an image that shows the error:


The relevant lines from the event handler in the Lua script are the following:

Code: Select all

function handleattacks()
  global.attack_data.until_next_attack = global.attack_data.until_next_attack - 1
  (...)
end

factorio-current.log contains the following:

I don't know how these backwards-compatibility bugs are prioritized, but it would be neato if you could continue playing old campaign saves.

Thanks for the report and the save.

It has been fixed and you should be able to load your save game again in 0.12.4.
