Hmm, now that you mention it, it may be because some of the staircase was already a part of the map when I made it. Didn't happen more than once either.
Let us all hope it's the case, hehe. I don't like peaceful mode, but I don't like mob to screw up with stuff I've put down. On my personnal server creepers don't cause blocks to be damaged, and I am thinking of modding my single player worlds to behave the same. I wish there was an built-in option in the game for this (a difficulty between PEACEFUL and NORMAL... say... "easy"). I mean I do want mobs. I want them to endanger my life, and scare me in dark corners, but I do not want them to mess with the time spent on construction. I have little time for re-doing things I've already done. Losing items on death is meh too.
This is why I quicksave every 10 seconds in most games I play. This is why I hate games with "check points" and "save points". This is why I have a hard time going back to the old games I used to play as a kid on NES and such. I guess it happened at some point as an adult when I realized I don't have enough time to do the same things three times. I just want to go forward. I don't find it rewarding anymore either to "finally win after trying again and again". As a kid I was like "wow I finished Contra, what an achievement, after all these hours spent dying again and again". Nowadays I finish the same game after dying again and again and I'm still just p***** off that it was such an unfair waste of time. Game design tends to go in this "kiddy" direction too when think about it; everything is about gaining benefits, very little penalties are allowed in modern games. You go from losing XP when you die in Diablo 2 to losing a bit of item durability as a penalty in Diablo 3. You go from Civ 4's choices of civics to civ 5's "only positive aspects" to gaining new social policies...
Um. I derailed a bit there.
EDIT: This very second my username changed. You're not dreaming
