Like the reports I made on the signs and painting, the bedrock part of the end crystal uses the old bedrock texture for some reason. And like the other reports I made, I have retextured them to look like the new texture for Mojang. Here is end crystal texture with new bedrock texture on it, if Mojang fixes it.
Edit: I made a new item texture for the end crystal, Just saying. Idk if Mojang will use it or not, I just put it here
