Title. May only be caused by the taldarim/forged stargate building skin. Not affected by graphics as I’ve tested it on low high and ultra.
This has happened about a half dozen times to me now although no one I’ve talked to has reported ever having this issue.
Has repercussions as if the second unit is a phoenix the spore can be delayed, if the first unit is an oracle the spore must be made very quickly or drones will be lost. This means sometimes there is a randomness factor on when a spore needs to be made if at all.
