When Immersive Aircraft and Flan are installed, there is no way to allow the player to use immersive aircraft vehicles within a claim. They are always prohibited from using them and there is no way to change that..

Fabric 1.21.1, loader 0.16.10
Mod version: 1.2.2

And you added it to the interact whitelist? What did you add specifically and what exactly does work?

In my testing I’ve found that allowing players to interact with boats, minecarts, and with things like armor stands, doors, and trapdoors, as well as animal interaction all do not allow the player to retrieve their vehicle.

Further elaboration: the issue takes place mainly once the vehicle has landed in the claim, and once the player (who’s not the owner of the claim) leaves the vehicle, they cannot re-enter despite the aforementioned being allowed through flan configuration menus.

Adding the aircraft to the list via /flan menu works for me. How did you allow it exactly?

ah I see, you have to add it to entity interactions. I see. It now works. Closing post.

Thank you
