Put the summary of the bug you're having here

I expect the beacon to have a repeating effect that never goes away if i am close enough and there is nothing blocking the beams

What actually happened was the effect would kick in for seven seconds then run out. Then a second later would kick in again and this would repeat even though i am right next to the beacon and there is nothing blocking the top

You could easily reproduce this by simply making a beacon (mine is full, don't know if it matters) and initiate an effect. Then just stand near it and you will see the problem occur
