Modpack: Medieval Minecraft version 1.19.2 (v20.5) - Fabric 0.14.19
Travelers-Backpack version: 1.19.2-8.2.18
Bug: Shift-clicking empty bucket into backpack crashes my game and generates a crash report. Previous version did not have this problem for me, and happened for the first time right after I updated to most recent version of the modpack.

When I think of it: I did not try other backpack types. This crash occurred when using the Lapiz Backpack, though I don't believe that should really matter, but, just in case, now you know.

And it's not a one-time occurrence, as I have 3 logs from 3 attempts. I now drag and drop empty buckets manually.
Other buckets are fine.

update to 1.19.2-8.2.19

Nice, that did the trick.
