[2.0.72] Crash of server loading save (LabelStyle::getFont)

[dje4321]

Trying to setup a modded factorio server however I keep running into a SIGSEGV fault when launching the game. I can ONLY get this error to occur when specifically starting a multiplayer instance. Launching a SP instance of the game will not run into the issue.

Attached is the server log, the save file, and a 7z compressed coredump file generated in GDB after setting a breakpoint at the signal handler as I couldnt get one to generate otherwise. (Not really worried about secrets leaking. Already invalided my auth token)

Server launch arguments

./factorio --mod-directory ~/.factorio/mods/ --start-server ~/.factorio/saves/server.zip

System is Linux running NixOS 25.05 on a generic HP intel laptop. Latest release of 2.0.72

This is a bug with the engine and not handling some of the mods you're using in a headless server context. It's now fixed for 2.1.

That is good to hear because I was looking forward to some of these mods. Now to wait on the update
