Would you be surprised that I would have done something similar to that, if I would know how to replace that darn forge anvil on the loading screen? XD
Also fun fact, whoever made that ORIGINAL Forge Anvil Art made it so it flips you off with a middle finger. Later apparently that got found out, and they made sure it doesn’t do that anymore, while still keeping the overall GIF.
Just grab some older Forge Version if you want to see it. I think it was the earlier 1.7.10 Builds of Forge. The up to date ones of 1.7.10 aren’t affected by this hilarious thing anymore.
