Not desirable position sampling for objects

[MhdMohammadi]

I am using scene grocery_store_convenience and task buy_alcohol. To initialize the task, the agent is sampled on floor, in grocery store. However, the initialized position for the agent is outside the building, as a part of the floor of the scene lies behind the wall. In this position, the robot gets stuck behind the wall, and the task will be infeasible to solve. A video of this case is attached below.
