Help Battle errors

[George]

If you've just beaten Rosalind, you're not able to check that problem, because it needs HM08 (Dive), only obtainable after further events.
Even so...

I think it is an actual spoiler for those who didn't play this yet...

Although it seems quite far from Venesi, you only need one to two minutes to go from Venesi to the black rectangle, where the pirates attack you. The gray arrow denotes the way I went to avoid them, and I still don't know why it worked...

I'm almost sure that I am the only one who is experiencing that problem, and I don't see anything that could have caused it... except that I had "sprite issues" in early double battles, but I don't think they are related. This is an example:

Harptera is not the bug, because it was under the "taking damage" animation. The actual bug was Chainite, whose sprite should have fallen because it had fainted before attacking Harptera. I called it "Ghost/Panthom Sprite" (Sprite Fantasma), and occurred several times.
(Puns about Harptera not being bug and Chainite being ghost are unintentional)

Moreover, I really intended to post this on the Bug Reporting Thread, but I preferred to make a separate post instead, because it was very extensive; and I don't think it needs to be reported there if it is not a general problem...
