Verisium Ore

I've Tested it 2 times after i noticed something went wrong with verisium Ore in originator map, it looks like when you upgrade mob from the verisium ore encounter (channelling one) using memory of suspicion (probability to upgrade normal to magic or rare), the event doesn't end even tho there are 0 mob remains in the map.

Edit : I don't know if it have any effect on that but i had delirium, beyond, every node of ore active aswell
