Good day, I'd like to report an issue with the Mod. So I decided to used the Mod alongside the Modpack called "All of Fabric 3" and every time certain items(ie: Space Helmet & Leprechaun Hat) in the Mod "Give me Hats" is dropped on the ground or if the player dies, the game would crash. Here are the different crash logs that I got when I was testing out the problem and recreating it.

First Encounter With the Problem

Disabled CTM but didn't Restart Minecraft

Restarted the Game after I disabled CTM

 When I took CTM out of my mods folder, I was able to enter the world where the problem occurred.

Specs
CPU: AMD a10-9700 APU 4C + 6G
RAM: 8GB 2400mhz
GPU: Integrated Graphics (AMD Radeon R7 Graphics)
OS: Windows 10 Pro 64-Bit(10.0, Build 19042)
Version of All of Fabric 3: 2.6.10 (Modifications: I added Sodium and Indium because my potato, or as I would like to call it, My PC, can't handle the mod pack smoothly without those 2 additional mods)

PS: This is what the member of the AOF team said when I asked for help and reported the problem, I understand that this may very well be caused by user error 'cause I'm not smart. Thanks for the time reading and giving attention to this post. Have a good day.

Thanks for the report. From what I can see "Give me Hats" isn't open source (although they have a GitHub repository it's empty?) so I can't see exactly what it's doing with its item models, which will make solving this a lot harder. Either way, I'll look into it and try to fix the issue.

The creator of Give Me Hats has put up the source and fixed the bug in the latest release of the mod (although I haven't tested it myself). I'll leave this issue open for now just in case more related bugs come up and since AOF 3 hasn't updated to the new version yet.

It seems like AOF has updated the mod in one of the newer versions, so I will close the issue. If you notice other bugs with this mod, feel free to open another issue.
