Strange behaviour of Lua function (City):inspire_partisans(plr): returns 1 for plr=owner and 0 for other players. Moreover, on certain conditions it makes client to fail. Fragment of console output:

1: in citizens_nation_get() [citizens.c::83]: assertion 'pcity->nationality != ((void *)0)' failed.

Maybe that is because I have taken Mali in editor but it somehow stayed a computer player? That seems wrong but I don't know, that's why I put the bug into Client category.

#1 Updated by Marko Lindqvist almost 2 years ago

inspire_partisans() require omniscience, the client has not (and shouldn't have - no support for cheating) all the required information.
The solution is probably something like moving inspire_partisans() to server only side of lua.

#2 Updated by Marko Lindqvist about 1 year ago

Attached patch keeps the lua API untouched, but when called from the client side inspire_partisans() return FALSE also when it cannot determine correct answer.
