Parts randomly being destroyed when testing the game

[jogamerforgames2019 (Shadow Slime)]

BEFORE: (Studio)

AFTER: (during playtest)

Console: (note that i indeed changed the place of the characters to try to see if it still worked thats why it has a .Model in it)

I do not have scripts in these parts nor even coded anything to destroy them
but i realized something. these parts were duplicated from a folder and parented into a new folder
this is the exact same behavior that i used with my cameraPositions folder and the same thing happened.. thought it was a bug.

and BTW
even changing the location of these parts wont help
and these parts are anchored

Expected behavior

For the parts i have in these folders to be there when i playtest

its probably falling through the floor. make sure its anchored and can collide is on

Agree with @ChildsplayVance. If this doesn’t work try setting streaming enabled to DISABLED in workpace.

If you aren’t familiar with streaming enabled I would recommend reading up on it here:

Instance Streaming

There are benefits to keeping streaming enabled, especially as your place gets larger and has more instances, so simply disabling it might not be the best long term solution.
