Actually, it has nothing to do with the 100% - it's the single german word making it bigger than in other languages (two words in English, and it seems to be comfortable splitting up Japanese at any character.
Let me ask you - do you think, given the height of most phones, to have character + level on the top, with challenges below that? Should still all appear on the screen at once.
After getting the level up message and evolving kaochan while on the dashboard, the adventure panel still shows the previous evolution of kaochan. It doesn't update until after leaving the page and coming back.
Just got my levels caught up to 10 after you fixed the points bug, and noticed a bug with the level up announcements. After leveling up to 9 and getting the notification I could evolve, I decided to do it later and closed the box. After that, I got the level up congratulations popup on every page I visited until I evolved my kaochan.
