I've read a lot of messages concerning the bug with missing textures but still don't understand how to deal with it 
. I'm playing on my private MC 1.6.2 server with such modes:
- Minecraft Forge
- BuildCraft
- Industrial craft 2
- RailCraft
- Forestry
- Iron Chests
- ComputerCraft
- WholeTreeAxe
- Smart Moving
- Code Chicken Core
- Immibis core
- Player API
Client mods:
- Render player API
- Rei's minimap
- Armor Status HUD
- InventoryTweaks
- Status Effect HUD
- Not Enough Items
- bspkrs Core
- MouseTweaks
I've already tried to install the fix from MistrX, but game crushes because of the incompatibility of that fix with Railcraft or Forestry, don't remember exactly. Please, guys, help to beat that damn texture bug!
