Try a combination of approaches, e.g., the dummy approach and the no geometry approach, if you can get the placed shipyard to replace itself on creation, this approach would fix all the problems with utilising no geometry for the placement object seen as it's forced to be placed only on the dummy. My suspicion though is that you can place a structure anywhere ontop of the dummy, resulting in a shipyard being placed not exactly in the right place, another possibility is that since the structure will have no geometry, the game engine may not identify when you have the placement over the dummy. Like I say though, where there's a will, there's a way

If you can build movable units just as you could structures, here's an idea. Make the shipyard a vehicle, with a special locomotor. This locomotor has speed 0, It's BehaviorZ="SURFACE_RELATIVE_HEIGHT" and its PreferredHeight="0", if things go well, it should stay ontop of the water, regardless of the depth and it shouldn't be able to move. but of course, part of this problem is not being able to place on the water in the first place right? in which case, some sort of deployable structure may be the best option, perhaps though, if the structure has no geometry it might work, if it does, you could use a granted upgrade or death timer to replace the building with the right version that has geometry. Another option, would be to use the Scrin Growth Accelerator method. Have preplaced objects on a map where a Shipyard can be placed, all you have to do is set the Shipyard's BuildOnRequiredObjectKindOf to the kindOfs corresponding to that special object. It would work very much like Act Of War: High Treason's method.

Okay, going from vehicle to structure or structure to vehicle is fine using the ReplaceSelfUpgrade module, going from structure to structure however, either results in the structure turning into nothing or crashes the game, anyone get it to work properly?

Any thoughts on trying squads within squads?
