Ores not replaced by Hourglasses after entering Mirage

While running maps, ores were not replaced by Hourglasses after entering the Mirage. Instead, they remained normal ore nodes and could be interacted with the same way as on a regular map.

Steps to Reproduce:

Map: mausoleum
Fragments: 2 z kalguran, 1 x guarding riches, 2 x monstrous lineage

1. Enter a map that contains ore nodes.

2. Trigger and enter the Mirage.

3. Locate ore nodes within the Mirage.

Expected Result:
Ore nodes should be replaced by Hourglasses inside the Mirage.

Actual Result:
Ore nodes remained unchanged and functioned like normal map ores.

Frequency:
Occurred in 3 maps in a row.

Notes / Question:
Unclear whether ores are guaranteed to be replaced by Hourglasses or if this is only a chance-based mechanic. If replacement is guaranteed, this appears to be a bug.

Not a bug. The hourglass is a rare outcome from ores in mirages.

I'll reiterate: You only get the hourglass occasionally. I've gotten several of them since the league started, but I get plenty of "normal" ores inside mirages too.

Understood, I thought it's a bug because I saw plenty when it didn't work and none since they fixed it. Good to know I'm just unlucky.
