Error: placement of fireweed in the air

[PatrikLundell]

Describe the bug

When passing just outside a research facility I got these two error messages:

DEBUG : Setting furniture f_fireweed at (9,17,3) where terrain is t_open_air (which is_open_air)
If this is intentional, set the ALLOW_ON_OPEN_AIR flag on the furniture

I have driven about two ticks from the error report presentation in the save (and the car is moving along).

Who knows?

Expected behavior

Not trying to place plants in the air.
