The personal light/glow that used to be enabled with the dark nights has been enabled again after the 1.30 badlands update and is still present after the recent hotfix today, It was not present in the experimental servers and there was no mention of it being enabled in the 1.30 patch notes so i'm assuming it was accidental code regression after the big update, There was also no mention of it in the hotfix patch notes today but i assumed because it's not technically a bug or a glitch that it would of just been turned off without needing to mention it, I know my other post got set to "Assigned" which i think means a dev was going to address it and fix it so i'm still hoping it will be disabled with the next hotfix.
I'm playing on the Chernarus map also i cant say if it's present on the other maps, It's incredibly distracting with the bright nights and ruins the immersion seeing a glow of light on all the objects you stand close to, It's not needed anymore now that the nights are bright and detracts from the gameplay experience i hope it was just an accident.
The attached screenshots don't show it very well but you can see when i'm standing close to the door and wall they are illuminated.
