Hi, I'm trying to replace the boat light with no luck. I have the new cut helidium piece, and I can jump to the top platform with no problems, but I can't get it to take the new light. I've got the new light in my hand, and I've tried hitting E and LMB from multiple places near the light stand with no luck.

I don't know if this means anything, but I saw on a Youtube video that there was supposed to be an old burned out light in the light stand - in my game, there was never a burned out light there, the stand was just empty.

Any suggestions?

I had the same problem that LeonMe had - the old light just wasn't visible, problem solved - just remove the old light by hitting E while standing near the empty light stand, then replace with the new light.
