Has anyone ever had an object disappear after a certain amount of time?

I made a simple object in UPBGE using geometry nodes. I then set it to spin extremely fast and have an extremely bright shader with a lot of bloom to mimic the appearance of a neutron star, complete with a blue-white colour.

The object strangely disappeared 1.5 minutes later when I tested it. I deactivated all scripts on the object but there was no difference.

Have I found a bug in UPBGE 0.36? Has anyone else ran into self-disappearing objects?
