When I try to view my pets in reserve (recently built, sent 5 pets there before I realized there is a problem) I get a blank page with following error:

Oops - The Following Errors Occured

• Invalid pet specified. (ERROR#102

This happens when I try to view their individual pages, on pet tab -> reserve I see their portraits correctly.

It seems all of them got this glitch. Their numbers are: 120344, 151332, 160433, 119084, 407003. Please help? I hoped to at least be able to browse what genes they had.

Hmm, I just tried it with my own reserve, and it looks like this happens if your reserve is set to Private. Set it to Public, and it should work fine. 

Thanks a ton! I didn't know there was an option like that, but it did solve the issue :).

Sorry that it takes so long, we're still working on the issue. Sumatra_Echo is correct, private Reserve hides the pets from their owner as well, so making it public temporary allows to bypass this bug.

This issue is now fixed

Wow, thank you so much for quickly resolving this :D! I changed back to private and it works perfectly now. Well done ;).
