Falling for all eternity in similacrum

[Xenyol]

I was messing around in the similacrum and noticed how it was possible to spawn in the dargyn flyers. I spawned one in and wanted to fly around for a bit. however, when i flew over the void that is underneath the similacrum, I kept losing altitude until i was well under the map (black squares were visible around the smaller white one which held the similacrum). I tried jumping out of it because I thought it'd kill me and reset, but no.

I know this is just in the similacrum, but still I thought like sharing
