Thank you for playing XD... admitedly this game still has A LOT of bugs XD...
We don't have enough time to polish it :')... yes the workshop one is know bug, I kinda messed up the settings before make the build :')
Ah for the cannon, that's nice info, the configuration must be slipped :')... but for now the house and the cannon has no use :'), for the next update for sure we fix that XD
Wait... the sawmill and brick stop working? ._. might need to figure that out ._., well basically the building will stop working if there's no available space to output the product...
Thanks for the feedback XD... that's really helpful <3
