Just so people know, don't EVER leave anything in front of a minehole-ladder atmo and then logout !
The fix for the exploit is that you now can't get stuck while entering or leaving a minehole, problem with this as we found out is if someone places an item, or stands at, the ladder (down in the mine) noone can enter it.
And yes I know people will now try to piss people off by entering someone elses mine and place items there, but this is just a warning for the other people that it now can happen.
And this also makes for REALLY good Vaults were you can't enter at all...especially not if they've mined out a big area and brickwalled.
