Annoying problem with lights.

[Hypercube]

So I know I created another thread already earlier today but I guess that one didn't matter so I'll ask a different question. What is this problem with lights that I have in the editor, for some reason spotlights named SpotLight_startroom (only 2 of them) won't aIppear in-game. They worked the first time I placed them there, but since I changed the properties of the lamp that has the connection between the spotlights, they won't work. I got rid of the connection, they don't work, I remade them, they don't work. Only changing their names will make it work. So what's wrong with the name SpotLight_startroom now, it doesn't make sense.
