What happens when an invisible creature physically interacts with a minor illusion from the perspective of that creature and from the perspective of another creature that is looking at the illusion at the time?
Would it be revealed as an illusion to other creatures?
RAW, any physical interaction reveals it to be an illusion, but it doesn't say to who specifically: notice the text uses "if a creature" not "if the creature".
On this basis, it would seem even interactions from invisible creatures may make it clear to other creatures that it's an illusion (perhaps because the illusion ripples on the surface). It seems to be missing something like, "if a creature sees itself or another creature physically interact with an illusion then..."
