Idk why but while farming in my house on PC it randomly stops allowing me to change the gralat states(lock etc) after a few minutes each time.
I have to re-enter my house every time it happens to fix it
EDIT: Seems to happen whenever I'm in a position like this but not too sure
(Same thing happens if you stand next to the gralat while trying to lock it which makes you open your profile)

Also, I get the "Are you still there" message every single time I stop moving for like 3-4 seconds to lock a gralat, it's pretty annoying
