hey guys, 
well im asking for help cause i see such hmm nonsane first time in 2 years  
so everything was fine and then sudenly all moving objects lost theyr's collisions   
down here is one script from meny others,that was working before and now gates got "ghost door" function ;D 
i tried this 
isLowLOD: A bool value specifying if the object will be low LOD. A low LOD object has no collision and a longer draw distance.  
cacaca = createObject ( 2909, -2199.2, 1074.4, 60.3, 0, 0, 356, false ) lits like that ? if it is,then bool true or false does not change anything    
  
     local ciec = createMarker (  -2199.2, 1072, 59, "cylinder", 3, 0, 0, 0, 0 ) 
      cacaca = createObject ( 2909, -2199.2, 1074.4, 60.3, 0, 0, 356, false )    
         
function cavegate (hitPlayer,matchingDimesion) 
  
  moveObject ( cacaca,2909, -2198.8, 1078.8, 60.3 )   
  outputChatBox("Cave Gates :",hitPlayer,0,255,111) 
  outputChatBox("Opening",hitPlayer,255,255,111)   
  setTimer ( cavegate1, 10000, 1 )   
  
  
end 
addEventHandler ('onMarkerHit', ciec, cavegate) 
  
         
function cavegate1 (hitPlayer,matchingDimesion) 
  
  moveObject ( cacaca,2909, -2199.2, 1074.4, 60.3 )  
end 
  
 
cya and thaks for help !
