All of the beta 3 mod kit levels and cutscenes now publicly archived with all of the issues the full game mod kit creates while loading these. These will usually end with a crash if you try to play them with out doing some slight tweaking to the level to get it to play nice with the Fullgame modkit
IF THE LEVEL CRASHES THE MODKIT. STEP 1 REMOVE ALL BP_FRIDGES. STEP 2 ADD A BP_HUMAN WITH AUTO POSSESS PLAYER OR WHAT EVER ITS CALLED. AND SET IT TO PLAYER 0 Level then should Load in a broken but playable state. from there its up to you to figure out proper restoration work
