I think I found a bug (Not sure whether related to device age) Game won't refresh page when wifi is turned off alsoo use enable wifi as transmission to saving
1. Cliick wifi off for save
2. When game is saved turn wifi back on .
IF save doesnt work dont panick just repeat 1 and 2 if that doesnt work panick ... jk jk
3. check save file Save.json
4. dowload fille again to make sure its save
5. Now its safe to close page.
6. Your welcome iphone and android users. btw samsung u were doomed from beginning.
