I don't know if I'm the only one, but I'm checking that, at least, Omega Souls, Paragon Souls, Yellow and Red Drops are not showing up on the ground.

Omega and Paragon Souls no longer spawn the glowing ball on the ground.

Yellow and Red Drops (like the ones left after killing a monster with the Yellow Circle around it, symbolizing that it will drop a Saddle).

As for the Omega and Paragon souls, they drop on the ground without any shine.

As for the saddle, I can't say, I killed a Lymantria with the yellow circle and tried for a few minutes to look for something that had dropped, and I didn't find anything (I lost the saddle).

As for the yellow and red drops, I'm in the desert of Ragnarok trying to drop items, or quests for my Edward, and I found it strange in almost 30min of farming, not having dropped any "yellow" or "red" items and then I noticed this happening with the Lymantria
