Love to get straight up lied to by a Minecraft mod that refuses to let the instance run because it sees I'm using Quilt instead of Fabric, when the two are, near as I'm aware, so close to each other as to be nearly interchangeable in any modded instance, barring a handful of exceptions in mods.
Also, not to be kind of a bitch about it myself, but this is just a "fast leaf decay" mod. There are literally dozens of these. Weird place to put your faux-principled rant about how you're mad re: people rightly recognizing that one of the head devs of Fabric is so transphobe brainwormed that they rejected contributions from trans devs on principle. (this is the most immediate and succinct piece I found on it but just googling "minecraft fabric transphobia" backs this up A Lot)
Stay mad, I reckon.
