reposting here the same thing i segnaled with the bug button: (with some paraphrasing to make it more readable :P)
in the summer's day quest, the sinking in the water sometimes is still active even when the glitch is out of the water
-sometimes it happens when i jump while falling, coming in contact with the water but still managing to do a last jump, making me sink while still in the air
-it also happened when i managed to land on the other side of the water/lake, but must have touched a little the water, making it impossible to me to jump normally or to walk, while i'm on the ground
the second case like the first, gets 'resolved'/cleaned by self drowning in the water to reset the sink effect.
-an other minor thing is the last jumping puzzle before the ladder, the one with the 3 miniplatforms appearing under the lights
in that one often the first platform doesn't appear in time under my feets like instead the other 2 do
this is really minor, and not that bothering, but on the same lag conditions the first platform reacts more slowly than the last 2
