What is the last version you've played?
If its 0.9(0.95 i think?)
On your file manager/explorer
Go to Android>data>adastra.game95
On that folder, select the folder named files then move it to adastra.game010
If the folder exists in adastra.game010
Just delete the existing first then do it again
I've already commented here about that and i think the developer is already seen it and in the next version, its fixed
