Thank you to every one in the community who has put suggestions and reported problems on the forums, it's been really helpful and this update addresses some issues
New Update:
You can now set Hunters & Seekers to be purchased automatically similar to the Auto mowers
Fixes:
Upgrade costs now match the displayed values
Purchase costs of Automowers show the correct values
Seekers now have their own purchase set (so if you buy 10 Auto mowers it wont effect the costs)
Hunters now have their own purchase set
The X movement icon now has a black border so it stands out on grass dyed white
The map size has been enlarged
