Lua error when an AI wiped out another AI in endless game (nog fog of war) :27: attempt to concatenate local 'name' (a nil value)

[Hans Joachim Desserud]

I played a game with two other AI players, and selected "Endless game (no fog of war)" as game type. I didn't do anything, but I watched the AI players as they expanded and fought. Finally, one of the AI players wiped out the other and took over the last military buildings. At that point, I received an in-game message with the following message:

Error in Lua Coroutine
[/home/user/widelands/src/scripting/scripting.h:45] [string "aux:win_condition_functions"]:27: attempt to concatenate local 'name' (a nil value)
Send message to all players and pause game

This was also printed in the terminal. I assume it attempts to print the player name, and AI players might not have names?

No, this is not the case. 05_endless_game_foless calls
check_player_defeated without setting the wc_name and wc_ver variable.
This nil values are passed on to make_extra_data which then crashes.
This would also crash for human players.

Peter, I assign you because those modifications and the win condition
are done by you, so I guess you know what you intended.
