It's cause your character... died. I'm so sorry D; lol I'm kidding
Try going into your options menu and check your video settings. There should be a Water Reflection option for you to check. Hope that helps
Actually that turns the water into the IW water x3 I should know because I have it on to reduce lag xP Anyway, have you tried re-installing the item pack or game?
Theres two ways to re-install the game:
1. Start Menu > Control Panel > Programs and Features > FeralHeart > Uninstall > Re-install
or
2. Computer > Local Disk (C:) > Right click the "FeralHeart" folder > Delete > Re-install
