Kingdom Chess bugs

Errors in Kingdom Chess, again.

I opened some t-shirts, weapons and stickers, but now these some things didn't open... and I opened these again....

For Example - I opened this helmet, but now it close...

I opened 4 stickers, but now opened only one stiker...

I opened helmet and sword, katana.


But now I open these once more...

It's very strange

I think this error is because I played this game on my second Android phone....
And some things save only on local storage in phone.... its bad...


What do you think?
