Duplicate Emerald spawn oddity in Cascade Falls Zone

While playing CTF in a server at Cascade Falls Zone a few days ago, I found this emerald, strangely floating in the air.
It was still able to be picked up, which I promptly did after.
Then today, I was playing in another server, and I found THIS emerald floating as well:

They're both at different spots, but they both could be picked up. I've never seen this before, and I was the only person that noticed it, since no-one rail'd me or even went after me with ring barrages.

Already reported, and this place has had wacky emerald spawns since the start of SRB2ME.
