Special SQM doesn't work while keeping distance!

Avoid = should not go, but may go if necessary
Block = must not go, it is possible that it go to that SQM when lag

I see you have added few new features to Special SQM system, could you explain what "Block" means?

BBot see a 'Block' tile as non-walkable (like a wall), but it is possible in lagged situations that it will go to that position. It's perfect to make blocks around a teleport you never expect the char to go, to avoid traps.
