No no, that’s not the bug. Basically, when I load my game I get that “unknown event id 10005” message, at this point I’m already on the computer menu (when you load a save you appear in that menu). Then, on the computer menu there is an option that allows the player to change the visual style of the borders and some more things (normally it is the first option on the second page of the sub menu Tools/Window, in the computer). So the thing is that, when I load my game, I get the unknown event message, and if I go to that option in tools/window directly, after loading the game I get the message again and the pop up menu to change the options doesn’t show.
Still, if I exit the computer and re-enter it, it seems that the option works again.
