Slug Seeker and log out glitch

I love slug it out but there is two problems in the game. First, the game glitches and logs me out and Id like to get that fixed please. Second, slug seeker modes chest opening is frustrating, ive tryed for 4 months to get a slug yet I still dont have him and that slug is Thuglet so I hope there is a way in the future I can get Thuglet with out waisting 4 more months. Thank you.

Yosuf big fan about Slugterra: Slug it Out!, v2.8.1
