Update to my problem:
A few threads ago I said I was getting an Error Message warning that there were long 1-4 interactions, having the program's progress freeze, and then give me EARLY_UNIT_END and start a new core. Someone responded, asking if it says it's been 3 hours since last checkpoint written.
Yeah, it does. This is exactly what it says:
[23:14:56] Completed 4750000 out of 5000000 steps (95 percent)

Also, it is always at 95 percent. This has happened at least 3 times, possible four.
