For 2 days now I've been having issues with certain gregtech textures, all the batteries, most of the circuit parts and the extruder shape plates. Others are experiencing the same issues and using other resource packs doesn't solve the issue, (screenshot in default, tried with Pyrolusite's GregTech Alternate Textures and a Sphax BDcraft pack). I was wondering if there has been some change that might have caused this.
Just checked, yes it is, i don't understand why redownloading hasn't fixed it if it isn't a serverside change. Edit: And it probably isn't hardware as others have it too.
Its an april fools joke I bet.. Last year Greg decided it would be funny to change all the textures of this blocks to troll face memes. It was awful. It should go away.. Last time it didn't go away for 2 weeks though so I'm not 100% sure.
If you don't care too much about your systems date, try changing it back or forth a week or month. That should do the trick.
