Confirmed. When a scroll destroyed an item it was correctly removed from the equipment inventory but the character kept rendering it, so you stayed visually dressed in something you no longer owned. The render now clears with the slot. Leaving IN PROGRESS until you have booked a real destruction and confirmed the avatar updates immediately, since this is a timing-sensitive path.

Closing this - Mark's v54 pass confirms the character stops wearing an item the moment a scroll destroys it.

Your diagnosis was exact: it was gone from the equipment inventory but still on the player. Emptying our equipped array only emptied the equip WINDOW. The avatar is rebuilt from an equip-changed event and the held weapon from a weapon-changed event, and a dark-scroll curse emitted neither - so a boomed cape kept being drawn on the character, and a boomed Pendant of the Spirit kept quietly accruing EXP, until your next equip change or a relog. Cosmic re-broadcasts the look on exactly this path: ScrollHandler.java:172-174 calls chr.equipChanged() when the result is CURSE on a worn item. Both events now fire.

One authentic exemption you may hit and should not report as a bug: a WEDDING RING is never destroyed by a dark scroll. ScrollHandler.java:137,159-165 keeps it worn and downgrades the result to a plain fail.
