[2022] Colored lights broken after update on 28-sept-2022

Hello,

Today we noticed a bug with the lights on maps in TM2020 after the game update of 28-sept-2022. Every light on every map defaults back to the white color.
It also occurs when creating a new map. When you place a light in your map and change the color to e.g. purple and calculate shadows, the light color is back to the default white color.

In the picture available at https://imgur.com/a/CypQ4X2 , the 2 lights on the left are Magenta and the 2 lights on the right are Default. Unfortunately all the lights look the same after Shadow calculation.
