You still see red outlines, even with Locastan's mod?
Hard to say, since I do not play in CB mode, maybe something has changed in XVM code. Maybe in the past all you had to do was to enable it in graphics window, and now we have to change some more colors in colors .xc additionaly.
Will investigate it further.
edit: Looked at the code, and nothing has changed in my configs. If you want to see colored outlines you have to additionaly install that locastan's mod.
