I broke the Cycad Tendril, I think the game designer stops its growth. If I understand it right it should be at 12 power because it has been deployed 12 times but it's stuck at 1 attack.
The descriptions for cycad tendril and cycad are exchanged. Cycad tendril is supposed to say "transforms into Cycad after 25 deployments", and Cycad is supposed to increase damage based on number of deployments
