If you use the "echo" comand within startup.lua the game crashes. stderr says: "Text has zero length".

The "draw_disk" function doesn't respect the draw order, disk are always drawn before quads.

Some command(s) I didn't find yet corrupt the loading of replays in intro mode. stderr then says: "Unable to open replay/somefile_thats_in_scripts.lua"
Found out that this only happens when the script of subject is loaded from the menu
