Finished the game!

Only took me 99 hours, lol! Not going to lie, dropping 5000 coins in one go was harder to achieve than the mega structures, mainly because the achievement is bugged. I found that going into temples and losing items to traps apparently works best. Also, for all who are still wondering - you do not need to have all 7 structures at the same time on your farm. You can make one - dismantle it - and then use leftover materials for something else.
