I don't know what happened, but do nothing but barricade now and look for wood.
I barricaded on the morning of day 1, when i transitioned from evening to night of day 1, all three boards of my barricade fell off...
The time barricade lasts seems to be random, but can be as little as 2 clicks of the clock, as evidenced above... With the new random time, you cannot find enough wood to keep the barricade up. Game just devolves into nighttime rapings and struggling to try to find a piece of wood to get a piece of a barricade back up, with every other aspect of the game pushed to the side.
