When version 1.05.350576 was released on TEST on July 27, it included some new tool tips about the Promethion Born ability. All of them were wrong. I immediately reported this in the bugs-typos-goofs channel for GalCiv4 on Discord. The game has been updated to 1.05.351507, but the tool tips are still wrong.
The promethion born ability has nothing to do with growth. It affects ships' hit points and removes their ability to heal.

It's the silicon ability that affects growth.

This tool tip that has been added has wrong information about the ability.

It should be Silicon-Based life instead of Promethion Born.
This means the tool tip for Promethion born is also wrong. It also contains a typo.

Here is another error of the same type.

Promethion Born should be Silicon-Based.
