If you try to use the Sub-Tachyonic Detector ability on a planet that already has the effect on it, the message is misleading/confusing. It says the target isn't valid because it's not been attacked / isn't irradiated. If the target meets either criteria but has the effect already on it, players may be confused by the messaging as-is.

ah yes, this is what I've experienced. Mistakenly sent a ticket thinking it's a bug about demon planet, or something.

Minor, but can be very confusing if you forgot to check the buffs.
