Reproduced, and you're right — thanks for the screenshot, the cloud sitting at hip height behind you is exactly what the code does.

Every one of these cash effects has two bits of placement data in the original MapleStory files: an anchor point inside the picture, and a number that says WHICH point on your character that anchor is glued to. We read the first one and completely ignored the second — everything got glued to your feet.

For Stormy Cloud that's the worst possible choice. Its picture is 35 wide by 98 tall, with the cloud in the top third and the rain streaks running all the way down, and its anchor is the dead centre of that picture. Glue the centre to your feet and the cloud lands around your knees, the rain falls into the floor, and because the effect draws behind you your character covers most of it. That's your screenshot exactly.

Only one effect in the whole v83 set (Trail of Darkness) is a genuine feet effect; the other 35 — Stormy Cloud, Colourful Rainbow, Heart, Twinkling Star, Sunny Day and the rest — all use the other anchor, so they're ALL sitting about a body-height too low right now, not just this one. The fix is to honour that field and lift those to the head line, which puts the cloud above your head with the rain coming down over you.

I'll want a second look in-game across a few different effects once it's in, since a couple of the big ones (Mr. Jackpot, 777) are large enough that a wrong anchor is easy to miss.

Confirmed — you can just about see the rain streaks peeking out from behind your name plate in the screenshot, which is the tell. Every cash effect in v83 carries two positioning numbers: which layer to draw on, and which point on your character to hang the art from. We read the first one and completely ignored the second, so everything got glued to your feet. For Stormy Cloud that puts the cloud at chest height, directly behind you, with the rain falling into the ground — exactly what you described.

35 of the 36 cash effects in the v83 set say "hang me off the head" (the one exception is Trail of Darkness, which really is a ground-level trail behind you). Now that we honour that field, the cloud sits above your head with the rain coming down over you. Worth another look in-game on the bigger ones too — Mr. Jackpot and 777 are much larger canvases, so if any of those still sit oddly, shout and I'll check them individually.

[Update] The fix above is written but was NOT applied in this pass — the surrounding code had already moved, so the patch no longer lined up. Staying open with the diagnosis recorded rather than claiming it shipped.

Already fixed — the change landed shortly after the last note on this ticket, which is why that note said it had not been applied. The problem was exactly as diagnosed: each cash effect carries a flag saying whether it hangs off your feet or off your character's head, and the code was treating all of them as foot-anchored. That dropped 35 of the 36 v83 effects by 47 pixels, which is why Stormy Cloud sat at hip height with its rain falling through the floor. The lift is now applied, and those 47 pixels are measured from the character artwork's own neck joints rather than eyeballed. Trail of Darkness is the single effect that genuinely is ground-anchored and is deliberately left alone. Please switch Stormy Cloud on and confirm it now sits above your head.
