Hi, thank you for playing the game and your suggestion!
I am updating the game regularly every month, in the next update I will be releasing balancing changes so that the map can not be fully filled.
Thank you very much for reporting this and the detailed description. I have fixed this issue in the most recent update, should be live in the next few days :)
I just found the bug after a bit of testing, it was a pretty major issue with the inventory that I should have found earlier. Thank you so much for mentioning it otherwise I wouldn’t have caught this bug!
