OK, thanks. I'll log in in a few minutes.
As a result, it would be necessary to remove the helipad furthest from the base (in the clearing behind).
It would also be necessary to remove two reset safes which do not belong to me but which were in the house when I took possession of the premises. These two safes are in a separate room and are stuck next to each other. I can't remove them as I don't have the code. In addition, it prevents me from returning two safes that belong to me and that are secure.
