Hi Shushuk,
I discovered during testing new bug. Don't know if it's only on 2.1 devices or any later but on my 4.X Nexus it's working correctly. Problem is that you start Locus, went to Shop and you see purchased items. When you then end Locus and then start it again, you don't see any purchased items. There is need to kill Locus with some task manager, then it will load correctly. Sorry for them, in next version it will be fixed. Maybe this do not happen for you, but just in case ...
