BorLog says

The legacy packer is indeed limited to ~2GB because it's using signed 32 bit ints for the tables.

But wow the timing... I literally just last night sent an alpha build for other devs to test.

It will probably be released in a couple of weeks

I rewrote the tables to use unsigned values, so it can pack about 4GB in 32 bit mode, and it also has a new 64 bit mode that can pack ~9 exabytes (about 9 billion gigabytes). The only catch is you'll need the latest engine version to run the 64 bit mode packs..

Error loading level list from data/levels.txt

is that line related to the game file size anyways? It doesn't seem to be the case, right?

@Mr.Q!, @Aerisetta,

The specific error may or may not be due to size, but regardless, exceeding 2GB with the current packer is never going to be stable. There are some hacky solutions I've seen out there in forks that basically just shove larger buffer numbers in and call it a day, but you won't get far going that route without bugs. Mine is a full rewrite of the packing tool and the engine's on board extractor.
