if ((!Core.GameMode.equals("LastStand")) && (rooms.size() > 2)) { bAlarmed = (Rand.Next(7) == 0);}This seems to be the (decompiled, could be flawed) code for alarm setting in houses, which is the same it was last build too. A major gripe I have with this is that alarms are not saved to the world files, and so reloading in a house, if you're unlucky, could result in the alarm going off even if you've already entered without one. Or at least, it's happened to me. A random number is generated between 0 and 6. If that number is zero, the building is alarmed. So there's a 1 in 7 chance the building you're going into is alarmed. It's possible that the random number generator's seed is creating results skewed towards zero, but I don't know a whole lot about So you could just be unlucky. Hey thanks, that's very interesting. Which file was it where you found this? I really should start learning lua. P.S. I guess I'm naturally unlucky. ^^
