[2.1.8] Vehicle equipment grid not saved to undo stack

[robot256]

What did you do?

Start a new game in Vanilla 2.1.8 and enable cheat mode.

Build a Tank and put fuel in it. Put any equipment in the grid.

With the blueprint tool, make a blueprint of the tank and place a copy of it.

Now right-click the first tank to mine it. Then Press CTRL-Z to undo the mining of the tank.

What happened?

The blueprinted Tank ghost is created with a fuel request, and when the tank is placed, the equipment ghost is in the grid. This is expected.

The "undo"-created Tank ghost is created with the fuel item request. When the Tank is build by a robot, its equipment grid is empty and the equipment that was in the tank when it was mined is returned to the player.

What did you expect?

I expected the blueprint and undo ghosts to contain the same equipment ghosts.
