Describe the bug
Items inside the backpack are lost when I chose to upgrade from normal backpack to Iron backpack

To Reproduce
Put Items inside Backpack, then upgrade it to a different material

Expected behavior
I was expecting an inventory upgrade (more slots) inside backpack (author never stated that, so this part is negligible), and that my items would not get deleted

Screenshots
No need!

Required informations (please complete the following information):

• Mod version: 1.17.1 - 6.0.0 for fabric

Additional context
I downloaded All of Fabric 4 for minecraft 1.17.1
The mod was inside that modpack

Issue confirmed, I'll fix it in the next release

https://www.curseforge.com/minecraft/mc-mods/travelers-backpack-fabric/files fixed in 5.4.1, 6.0.1 and 7.0.0

This happened to me too!

YO, A LITTLE UPDATE, its stil not working for me, but i tried to get into the game with the version 1.0.1, take my backpack out, and then open the game in 1.1.1, that worked for me, if its a server, you can try to make another backpack, put it with the option in the backpack, and then yake it out eith the option inbthe backpack, that worked for me at least, sorey if 8ts hard to understand:c
