The Garrison "units attracted" tooltip issue

Looked into this.

Essentially when a 3x3 Garrison is created an augre will be attracted, however the room displays that it attracts 0 units at this size. Likewise two 3x3 Garrisons will attract 2 augres but both will only display a maximum of 1. If the maximum units attracted is zero then the attracted number will be in black.

Rep steps:

1. Start Sandbox

2. Create a 3x3 Garrison
