Grand Mirror fruit in Precursor tower

Interactions involved:
- Delirium: double boss mechanic, where you can consume a fruit to apply delirium fog to a map area - Grand Mirror?
- Precursor Tower: the tower that just reveals nearby area.

1. After defeating double map boss, the fruit spawns and is not used.
2. Tower is consumed to reveal nearby area and to get a tablet
3. Going back to consume the fruit, no longer allows to apply delirium on any node nearby or with fog specific effect nodes.

Madox also despawned and is only visible on minimap.

Did not try a second time, as this was triggered via delirium tree and not sure if grand mirror can be put on towers by players.
