Describe the issue

When using the ponder menu for mechanical saws, one of the examples is of it cutting down a large tree. About half a second after it cuts it down, the game crashes. I have asked about this on the Create discord server, and they told me it was an Immersive Portals issue (the crash log says so) and that I should file a bug report with you instead.

If anyone needs more information to debug the issue, let me know, however I might not respond quickly.
