We ran this simulation after we fixed the cosmic-ray heating bug in Gizmo (after 2018-4-26). That bug erroneously applied a heating term from cosmic rays to all gas in the simulation at z >~ 8, which prevented gas cooling and star formation at those early times, and which affects other FIRE-2 simulations. This simulation unfortunately has some corrupted snapshot files, which are (essentially) unreadable. We list these below. There are no halo catalogs at these snapshots. (When we generated the halo merger trees, we temporarily replaced the halo catalogs at missing snapshots those those at with adjacent snapshots to ensure smooth trees with no gaps.) corrupt snapshots 316 317 318 319 320 370 371 380 381 433 434 435 436 437 438 483 484 498 499 571 572 585
