Alone
Reproduction Steps
Create a container by grouping a pathfinder and RRS object (this object was made before the selection bug)
Place Circuit chips inside the container
Save the room multiple times without interacting with this container.
Object Boards and Circuits disappear
Description
I put a studio object and pathfinder in a container and did some circuits. But after saving the room a couple of times, all the circuits inside the containers disappeared. The object boards were also gone. However, when configuring the object, I still had the option to delete the non-visible circuit board, so it just disappeared.
*Edit
I opened my room in RRS and found that the object board still exists, however, it was just at a position about a hundred units away. So, I would assume this glitch only affect circuit board positions.
