This loader fixes save (online, offline), glide, glide kick, grapple etc.
You can try this with your current save - but it propably will not work.
You need to start new game.
Make backups of your saves frequently.
Make backup on entering batcave (1st and 2nd time).
Known issues: On 2nd batcave exit (with cure and ultra batclaw) there
is flying/climbing/line launcher sequence on some rocks - after this - you back to
sewers - you need to see enemies and Ivy plants there.
If you not see enemies and plants - you encounter "wrong level load" issue.
Exit game (Alt-F4), restore 2nd batcave savegame and try again.
From there make backups of your savegames every time you see save icon (alt-tab)and if
you encounter "wrong level load" restore last backup save and load it 3-4 times to get
into correct level (with enemies and plants).
Except above - game is working fine and i just finished the last boss, Joker. He's very hard to beat.
