Campaign oddities Thread - Tiberium Essence Fans

So, as I am playing through the campaign (version 1.51 btw) I have noticed a few oddities.

First off, I recall having a conversation with Carnius on the subject many years ago, but I am not sure if it has changed since then or not, but...

Is any of the unlockable Intelligence Databases touched/changed on purpose? The answer was no in the past, but as I am looking at it now I can for example tell that the Grenadier Squad database entry in the GDI campaign has been changed to suit the Disc Thrower Squad. This is cool and I would love to see more of this.

Secondarily, and more noticeable is the campaign units themselves. At random during the campaign, some Tiberium Essence units are replaced by Tiberium Wars vanilla units, seemingly at random between mission to mission. What causes this behaviour? Is it fixable?

One example is the Nod mission "Outback" (steal nuclear warhead transports) where the Stealth Tanks reverts back to their vanilla TW (Tiberium Wars) versions, while the Scorpion Tanks and Harpies stay in their correct TE (Tiberium Essence) version. Another is from the Nod mission, "Ayers Rock", the Nod SAM turret. The build icon in the support structure tab reverts to the TW icon, and when placed you are prompted to place a hub and three turrets. The turrets are using their correct TE model, but they appear unconnected to the central hub but are unsellable. They do not auto-rebuild when killed. This often happens to the GDI Tiberium Refinery as well, as it often spawns the TW version, aka the "open and radiating pool of death". There are many more examples of this throughout the campaign missions.
