'Each of the six side bosses (Molgat, Asparn, Gatneri, Sipus, Flavi, Kutisen) has a 75 % chance to appear in a run, with an elite in its place otherwise; over 1,000 test runs that came to 4.5 of them on average. That is the rate the server has always used, not a fault, and the game data has no other figure. Whether to lower it is up to the server owner.'

i think 75% is too high spawn chance and on official server it wasnt the case. maybe reduce it to 33-50%
