Restore File Questions

[splash_]

What could be the issue when the restored session gets stuck (no progress is seen) + progress % jumps to roof?

$ rm testing_session.restore
$ oclHashcat-plus-0.14/oclHashcat-plus64.bin -m 3100 --gpu-loop=1000 --gpu-accel=800 -a 3 hashes/hashes.txt -1 ?l --session=testing_session ?1?1?1?1?1?1

AFAIK, restored session should pick up on 2.80%, right? The behavior I see is this one:

I ran it again with ?l?d?s?u saving the session on testing_session2 and it also got stuck/progress jumped (it jumped from 0.02% - before quit - to 21.68% - even though the absolute number is the same).

NOTE: for this post I did a quick check, but I already left the restored session running for some 10min - no luck there too. Stuck on 431615508480.
