Most unit descriptions list what a structure contains or what abilities are usable.
Wrong/incomplete ones:
- Nexus - does not mention Battery Overcharge ability
- Fleet Becon - does not mention upgrades for Tempests
- Overlord with Ventral Sacs - should mention the transport capability. The other race’s transports do that, too
- Lair - should mention that it enables Ventral Sacs for Overlords
- Lurker Den - mentions a single upgrade, but actually holds two upgrades for Lurkers
