would it also work if I link the savegame here?
I made a special savegame with Nomu the Marauder in the Old City (used console - bug happens with or without cheats activated). The boreal dwarf character named "Runajasko" has Essence Interrupter equipped (second weapon slot). If you crit Nomu with it (I gave him Ring of Focused Flames - use Flames of Devotion to produce a crit easily with +20 ACC) and then kill him he will spawn a creature. After it is defeated you will not get the original loot from Nomu. If you don't use the Essence Interrupter he will drop his usual stuff (unique ring etc.). For me it's 100% reproducable. Happens every time if "Experimental Souls" gets applied.
Here it is:Savegame
