When i first started the game, i had the orbital strike already unlocked. It only disappeared after importing a save.
The building texts sometimes don't reflect the actual upgrade status, for example hydroponics said it produced 80 gold per second, but the upgrade said it only produced 45 gold now and 80 next.
The fire rate upgrades on the main page seem to do nothing, only those in the tech tree.
I am unable to build turrets.
Mortar sprite is misalinged with aim point. Upgrading the mortar also had no effect for me.
It is unclear to me if the wall reinforcement is a healing or upgrade mechanic. EIther way it did nothing.
Miners seem a tad overpowered.
I have no clue what the Elite Guard description means with "Cost: gold %s"
