Don't tell me to learn the basics of java, I already know.

But Thanks everyone by advance to help me with this.
    • These forums are for Minecraft Forge, not Fabric. You would probably be better served posting this question wherever fabric support is given, most likely their discord server.
    • Add the new latest.log (logs-folder) with sites like https://mclo.gs/ and paste the link to it here
    • Update: I tried to reproduce the bug and found out that if I place a flare on a block and then dismantle it with the pickarang (Quark), the flare gets no NBT Tag after getting assigned an empty one through the offhand.
