The Sands of Time and Sigil of Power

Hello, so there's this interaction between The Sands of Time Tyrant's Sekhem and Sigil of Power where you cast a Sigil of Power, use some spells to procc the clones, a clone will recast your Sigil of Power and this clone's Sigil of Power cannot gain stages as you spend mana - probably because it belongs to the clone and not yoursef?
Thanks!

I also encountered this bug. Hope it can be fixed

I am also encountering this issue. However, it occurs even if the suspended mirages do not re-cast the Sigil of Power. If you prime them with a different spell and then cast Sigil of Power, they will re-cast the spell you primed them with and you will cast a single Sigil of Power but it will still not recognize your mana spent while inside it.

Same issue, am sad :(

Only way around this to just use sigil on a trigger?
