Crashes when multiplacking 80,000 sprites

I tried to pack 80k , 32x32 px images but it crashed in this line. If trim is off then it wont crash, otherwise it hits this assert. If I remove it I run into another error on the line above:
thread 'main' panicked at 'index out of bounds: the len is 130 but the index is 130', src/packer/skyline_packer.rs:51:34
