🐛 [Bug] Detect Magic not stacking

[Daribon]

🐛 Bug report

If 2 mages both cast Detect Magic (spellID 2855) on the same target, then only 1 Detect Magic will appear on the target.
The most recently applied one replaces the first.

Expected behavior

It should be possible to apply multiple Detect Magic on a target. One for every mage.
