I'm not sure what you mean exactly? Like, no new missions in the "Summoning Experiments" or in general? Since alt Hanako is the last one (assuming you did them in order), there should be no new missions for this "sidequest". If you mean the regular story maps, are you perhaps in the Land of Carnage? You can't progress the story in there for some reason, only play maps you've already unlocked/cleared (and the Item World)

o3o mmm good question , let me see .... erm , how i can post screenshots ? .....xDD

o3o well the thing is , i end the summoning experiments and the tutorials wich u figth the prinnies in the act one , but when i try to seek another mission the the panel of missions gets corrupted and i cant choose anything , maybe is a bug , because i play this game in linux? , linux mint ..... if i can post screenshot maybe or maybe i can post in my public screenshots of the game ,better .....

Hmm, yeah, that does sound like a bug, it's the first time I hear something like that. Other than maybe trying to check the game files' integrity (right click > Properties > Installed Files), I've got no idea

Since you seen to be rather early in the game, have you tried starting another file/playthrough to see if the same thing happens and/or if it's reliant specifically with getting alt Hanako?

o3o well i gonna try that , thanks
