Miscellaneous: Minor Illusion doesn't show for people who zoned in after illusion was cast

[Afterburner]

So I'm putzing around in NFP, mostly AFK, and decide to amuse myself by casting Minor Illusion. I hit F9 to see what I look like. I look like a street lamp. Solid. I go AFK for a bit.

People who have zoned in after I cast Minor Illusion don't see me as a streetlamp. They see me as an Erudite sitting UNDER the world, with only the top of my head poking out of the ground.

I obviously don't have a screenshot, because from my perspective I look like a streetlamp. But I've had several people comment now that it looks like I'm "digging a hole" or that they can only see the top of my head poking out above ground. And all of them zoned in after I cast the spell.
