I've figured out a mistake that does not affect your own mod but can affect others loaded after RH.

You are overwriting the BuildingBase vanilla element
<ThingDef Name="BuildingBase" Abstract="True">

and it is different from vanilla: it has different stats and has no thingClass.
This last element is the mod important thing.

It makes my mod "Self Launching Pods" and likely other mods not work at all.
Modded buildings will not spawn after construction.
Some people think it is my mod's fault but it is not. Maybe I should use my own BuildingBase but I think you should surely not overwrite this.

Please fix it ASAP. Change the name or something.
