2 of the achievements do not work and Ive tried everything and followed walkthroughs to the letter...sent devs an email to fix asap....update: spoke with devs and they stated they wont be releasing a patch/update to fix achievement issue as they say no one else has brought this to them but me...so I think everyone seriously needs to contact them so they will fix the 2 achievements that dont work for iOS users. They were nice about it, but if people dont advise the problems then how else will they know? This is a lesson in gaming people need to learn: as one big voice the devs WILL make the necessary changes if the majority of their customers lets them know their is a problem...without this, then devs can claim there is no problem and it never gets solved.
Update: tired of developers thinking they dont have to go back and fix their games problems...the game crashes sometimes on itouch 6 and iPad Pro, and 2 achievements do not work...spoke with devs and they refuse to do anything...they already have their money and are working on sequel to take more of your money.
