Is it possible that there's a custom column class involved? I've seen cases when it was used, funny things would happen when instantiating those, in unfathomable order, even the class level .init() being executed instead of instance's (which may not fire at all). I know I ended up with grids with lots of code in grid.init() and no columns set in the designer. At least I had control over the course of instantiation.
