I am a staff member on a private server of a game called dekaron and anytime we work on something big to put into the game we prepatch in a lot of big stuff so it can be worked on and the additional stuff be added later. Just because it shows a mission marker and discription doesnt mean the actual mission is in the game. Like the reef raid. All ot says is "reef raid" "reef raid discription" this was probably not finished yet and was/is still being worked on. Could be far from complete, could have bugs, many things.
