Crazy bright lights (in Ultra settings ?)

[Harest]

Hi,

So, i did a map (Twinster Helix if needed) for the MX Christmas Calendar Project of this year, for December 11th. On my end everything was fine, the lights are normal (screenshot). I'm in low settings, but i've a similar lights rendering in default settings, and.. even if i try to put everything up, like checking ultra lightmaps and lightmaps calculation on high.
Now, the same thing but from Riolu's POV, first a screenshot, and here is the video (starts at 1h47m57s). He has everything maxed as he told me, and bloom on medium, without motion blur.
The same issue happened on the map just before this one, a canyon one from Akiliyh. I don't have the replay however.

I thought it could maybe be related to a shader model difference but my gpu (ati 7870 2Go) supports shader model 5 so i don't know.

I downloaded the VOD to keep track of it in case it'll be deleted since past broadcasts doesn't last more than 2 weeks, or maybe 2 months for partners, not sure.

Any update on this? The video link isn't available anymore in the previous post but i still have the video locally if needed.
