Thank you for your feedback!
Yeah, for some stupid reason I forgot one simple line in all SSS upgrades and every idol that is tier S or lower as default have infinite stats :/ but it's fixed. Probably next week the new update is incoming with everything fixed. Oh, the bug that crashed your game as well- I'm sorry that happened.
The Roboco bug is new to me, I'll investigate it. Probably it's simple as well.
Also, thanks a lot for sending the bug report! <3
