[HELP] Lights

[Snake]

So, I was messing around with lights and got one working in-game. Well I tried to make a wider version and a flickering version by doing this:

ConeWidth         = 7.0

That's all I did and it crashed. Is there a width limit?

I also did this to a flickering one:

FlickerType         = 1
FlickerPeriod      = 2.3

Both caused a crash.
