bot is not seeing non pinned models when entering a room

[ssm2017]

hello.
steps to reproduce :
using the classic client, enter a room and spawn 2 objects : 1 pinned and 1 unpinned.
make a bot enter the room using the bot switch.
the bot only sees the unpinned object.
the unpinned object is not appearing in the a frame scene.
unpin the object, make the bot enter again and now the bot can see both objects.

is there a way to maybe refresh the scene or something else to make the bot see also the non pinned objects ? (or is this a voluntary behavior ?)
