[BUG] can't change the radius of bright and dim light

[shradee]

When I am trying to change the default option of bright/dim light, it breaks the light tool. It means, that I am not able to place any light source until I reload the map. And even after that I can't change the radius.

Tried fully uninstalling the program, deleting the "appdata" folder included. Nothing solved the issue

Thanks in advance
