Good day.
My name is Mickey Joe Alpha and I am the creator of the VanillaBDcraft resource pack.
Our resource pack has its own forum (BDcraft.net) where users can post bugs they experience with the RP.
When I started making this pack it was for private use only and I personally don't play with mods so don't use Forge, but since VanillaBDcraft has been posted to the public we have received a number of bug reports having to do with textures glitching. The pack makes use of vanilla Minecraft's random textures feature and uses this on stone brick.
I have never experienced this bug before and there's on this the users who had problems with the random textures was that they used Forge.
Of course it could be something else but I was wondering if this was a known bug as fixing it is out of my power.
Here are the links to what the users posted:
