Research Retreats (System Improvement)

Tooltip says:
+10 per cold
+2 science per planet with anomaly per relic

It appears to be:

+10 per cold
+5 science per planet with anomaly per (unassigned and temple relics)

Unsure if this is a bug or an outdated description.
Edit: Also, it's possible to build this in a system with no anomalies and no cold planets (giving 0 science). ES2 usually suppresses system improvements that do nothing.

Temple of the Lost (Planet Specialization)

Part of description says:
+400% planetary specialization industry cost on planet

If this is to increase the cost of switching specializations on that planet, it appears to have no effect.
