A little lua mod that announces to the chat that "A drill is inactive. Please fix it." whenever the situation happens. Found the code for it on the steam forums a while back and just actually put it together for a friend. The output can be changed by editing the lua file using a code editor such as notepad++ and replacing "A drill is inactive. Please fix it." with whatever you want it to say.
Installs like any other blt mod, just drop it into your mods folder in the root of the PAYDAY install directory and make sure it's checked in the lua mods menu in game. To uninstall just delete the folder from your mods and you're done.
