For all the years that i have been in df i have always known there ar3 guys that wont update until forced to..
They do this for a glitch like the guy on the ship.zup has removed it yet many still have it..
Now ive already talked to a few guys that a more than a few updates behind ever one else.

Now ive played other games where updates are mandatory.so everyone is on the same page getting and sending the same code as everyone else.the one biggest reason was to reduce game lag.(i.e.i did a couple of beta tests for some game)

We all have to take the good. The bad. And wheres the game updates.like the unity has created.
Zup is on it and doing what he can.the least we can do is help hime out.
Ill bet half of the glitches are due to people with out of date game info.
