[Gameplay] - Search for resources near a current location before the init-pos.

This should bring the behaviour back to pre-A24 and means entities will stray a lot less when gathering.
The entity will search close to the current position, which is mostly next to a dropsite.
When there is nothing found there, the entity searches nigh the initPos.
