DayZ-SA-Tomato/script/5_mission/m_missionserver.c(236):
Function 'OnPreloadEvent' is marked as override, but there is no
function with this name in the base class

I've just installed DayZ-SA-Tomato to my server for the first time. I followed the guide and am receiving exactly the same error message when launching the server. DayZ-SA-Tomato/script/5_mission/m_missionserver.c(236). What am I doing wrong?

I have these folders:

C:\Server\DayZ\DayZ-Sa-Tomato\addons\DayZ-SA-Tomato\scripts\5_Mission

and within there is the M_MissionServer.c

Question: Is it correct that I have the complete DayZ-Sa-Tomato folder (from GitHub) in the server root, and in the server root folder, there is a folder called "addons" and inside addons, there is another folder called DayZ-SA-Tomato?
