On version 1.6.33 of Forge, the multiplication of mana with more than one
Nyxbloom Ancient it's not working. I played
Rite of Replication paying the kicker cost, creating 5 copies of Nyxbloom. The Gatherer says the following about Nyxbloom:
"The effects of multiple Nyxbloom Ancients are cumulative. For example, if you have two Nyxbloom Ancients on the battlefield, you’ll get nine times the original amount and type of mana."
But when when i tap
Temple of the False God, it produces only 6 colorless mana, when the correct amount should be 2*(3^6) = 1458, like explained on Gatherer.
