I went to the house where he's at and hes not there....Its like hes gone from existance...Where else could he be besides Mimics??

I found out my game corrupted to the point of no return (I ended up trying to edit my save file so I'm assuming that could be the cause of it...I saved and got stuck somewhere then-yeah.) Long story short nothing I did worked and I had to delete that save file for a whole new one and now have to restart my game T_T

I should've typed this earlier but I totally forgot about this post OTL I'm sorry!

I have faced the same issue. The cause is you forget to defeat Squid Baron boss.
