Can't set player.opened to vehicle equipment grid?

[Jtmzac]

I'm swapping out a vehicle entity based on equipment placed in its grid, and if a player is the one to place the equipment then they will have the equipment grid GUI of the old vehicle open.
Destroying the old vehicle closes this GUI so to make it more invisible to the player I thought I could open the new vehicles equipment grid automatically.

However setting:

Code: Select all

player.opened = vehicle.grid

doesn't work at all. It doesn't close any existing GUI's and doesn't open the expected equipment grid.
I tested with a tank from the base game instead of my custom prototype and it doesn't work for that either.

Meanwhile

Code: Select all

player.opened = vehicle

works just fine for opening the general vehicle inventory.

Am I doing something wrong? Are vehicle equipment grids not supported? Or is this a bug?
