Aquilo factories concrete floor can be removed, revealing Nauvis ocean

[daniel-hoefer]

Factorio & Factorissimo version number
Factorio 2.0.76, Factorissimo 3.11.19

Describe the bug
On Aquilo, when inside a Factorissimo Factory building, the concrete floor can be removed (e.g. via Ctrl+x cutting tool, or via deconstruction planner) and Nauvis ocean tiles are revealed below. The concrete is moved to the players inventory.

As a workaround, the factory building can be removed and placed again without issues to restore the concrete floor.

To Reproduce
Steps to reproduce the behavior from a new save:

1. Start a new save with Factorissimo 3 installed.
2. Run command /cheat aquilo
3. Place any Factorissimo Factory building
4. Go inside and remove the floor via cutting tool or deconstruction planner

Expected behavior
The concrete floor shouldn't be removable. Removed floor shouldn't reveal Nauvis ocean tiles (makes access to water on Aquilo too easy). The player shouldn't be able to get an arbitrary amount of concrete by repeatedly placing and removing factory buildings and removing the floor. Using the pipette tool (q) on the floor shouldn't enter concrete floor tile placement.
