I've gotten this error many times since the recent Windows update. I'm on the Dev branch of the game with several mods loaded, but there's one mod in particular that I can recreate the error with without fail, Personal Arsenal. My friend has the same mod, playing on the same server, doing the same thing, but his never does it. I get the error mostly when closing PA but I have gotten it while entering it. I've gotten "bad_module_info" a few times leaving the map but it does not appear as often as the PA crash. It crashes both in singleplayer and multiplayer.
