My father and I run a VERY small server- the only people on it are me and one friend. I was excited to get 1,15, but I was quickly alerted that almost every mob had the wrong texture. Along with many other issues. So, we went in and /summoned every mob and animation to test things out.
Heres what we noticed
The problems started at the Bees: Bats ( the only mob before Bees alphabetically) were fine. Bees had no texture, and, aside from a few exceptions, every mob was pushed back one. (ex. Blazes were bees, cats didn't exist, c spiders were cats, chickens were c spiders, etc.) If needed I can provide a full list of every mob's texture.
Sounds were so messed up, we couldn't keep track. Enderdragons (that were actually enderman) made chest noises instead of roaring, the basic hurt sound was a pig, and cave spiders (that were actually chickens) sounded like cats meowing. I did not try to make a list of every sound, but I have a few written down.
Most projectiles don't have animations, and minecarts are all switched around, though the normal cart and the cmnd block cart just didn't have any texture at all.
Thrown items don't have an animation, nor do they show up on the ground. This is one of the more concerning aspects, surprisingly enough.
Some sort of item has been replaced by simply a "written book". We do not know what it replaced, but we had 12 of them.
A few other small details that were odd, but not game-breaking
We have already had a reset in this server, and it discouraged us from playing for months. We finally have made progress again and, frankly, we'd rather play like this than have to start over which is saying a lot considering the deafening enderdragon noises that follow us everywhere.
I am 14 and kind of dumb, but my father is a programmer so don't worry about confusing terminology.
Is there an easy fix?
How do I go in and replace every texture? Is there a way where I can just backdate the server to 1.14 again?
