[V7.6][Bug] Station Designer UI Persistence Bug

[chibiphoenix]

After some testing, I’ve managed to reliably reproduce a bug where the station designer UI persists in contexts it shouldn’t—specifically, it remains active in the background even after leaving the planning menu. This leads to visual/UI oddities and unintended interactions when buying ships or building new stations.

Steps to reproduce:

1. Load the provided save file.

2. Teleport to the Leap of Faith Katana.
3. Take a seat in the cockpit.
4. Open the Map.
5. Select one of the stations I’ve built (e.g. Protectyon Trade Hub in Windfall).
6. Click 'Plan Build'.
7. Right-click on any module and select 'Encyclopedia'.
8. In the Encyclopedia view, navigate to the 'Ship Interaction' tab.
9. Click 'Get Up'.

Observed behavior:
The player gets up and appears to return to normal gameplay, with no indication that the build menu is still active.
However:

• if you attempt to buy a ship, the station planning UI remains visible in the background.
• If you open the build planner for a different station, the previous station’s layout overwrites the new one.

Fortunately, cancelling the erroneous plan or reloading the game reverts everything and exits the bugged state.
