So staffs have been dissapearing since last september 2013. We've run multiple ways to get around this. The only time this happends is when the staffs have been Fully upgraded and then taken out of the Crazy place. We've come up with a solution to get around this and still complete the EE. It seems thousands of players are confused as to why this is happening. The following strategy:
There is a solution to doing the Easter egg 2 player, you must leave 2 upgraded staffs in the holdalls where you finalize the upgrade, one player use the ice staff and the other use the fire staff both players must build and upgrade these staffs separately, (ice staff is for getting the free zombie blood, fire staff is so you can place it in the excavation site holdall 4 times and taking it back from its build point to skip the placing the staffs in the robots heads step.
( I'm still testing it and trying to get around it but the idiots I'm playing with (Chris) keeps messing up. I'll edit this post if it is a fix.
