Tiviacz1337/Travelers-Backpack#1259
I reported this to Traveler's backpack, but the dev said the issue is on Trinkets' side so I'm reporting it here.

Describe the bug
with 9999 stack size, when I put in a stack that has more than 99 items, I get a crash as soon as I pause the game (log and crash report included below). I had two stacks: dark oak logs, which I have 211 of, and copper, which I have 124 of.

Write steps to reproduce the bug
Get a backpack
put a stack of more than 99 inside it
pause the game
it crashes

What is expected behavior
It shouldn't crash :v
