Summary:
Cobwebs become larger when held in first person view
Description:
When holding a cobweb in the first-person perspective, the cobweb model in the hand becomes very large.
I also tried this out with McStacker, a much more popular website. However, it had the same effect. This version is modified with Sodium 0.5.2 however, but I don't think that had much to do with it.
Oh, I didn't realize that. I also said that I was in singleplayer, but thanks for letting me know. I must have forgot that it didn't work, since I was doing this late at night and was tired.
I restarted the game, and it fixed the problem. It was still weird, though, so I can't get a world save now.
