Ok, first off, I'm a long time player first time poster
I've recently started to create my own modpack, and everything was going just fine, any errors we encountered had a corresponding logfile for us to dig through, and despite having nearly no knowledge of coding we were able to figure things out through common sense, and a bit of google, and correct our mistakes.
Eventually we ended up with a nice pack of personally selected mods running smoothly in both single and multiplayer modes. Long story short, after a few days of smooth play with no discernible issues, this is what suddenly started happening after a few days of smooth play...
Textures on certain items within NEI suddenly didn't exist, or were completely broken, in both SP and MP. I just don't know where to begin without any sort of crash report or logfile to cross reference with google.
I have MC 1.5.2, Most recent Forge (7.8.0.703), CodeChicken Core (0.8.6.6), NEI (1.5.2.13), and various selected other mods, including the two that seem to be broken in NEI, ICBM (1.2.0) and More Pistons (1.3.3)
It's a difficult problem to look up because it just spontaneously happened one day, never registers an an error, no logfile, no nothing, server says everything is fine too, and I've looked through the first few pages of "Common problems" to no avail.
If anyone recognizes a problem like that shown in the screenshot then perhaps we, probably just "you", whoever "you" will be, can figure out where the conflict is
