Yikes. That was unintended. I will push to investigate the cause of that during his upcoming week and see what can be done to revert it. Changing things over to Ranked mode affects a LOT of stuff and this is one of those that I wasn't aware of. Thank you for the report!
I think the arsenal switched over to the BI Arsenal instead of ACE arsenal at the two crates on base. Also the M27 isn't available at said crates only the M16A4. The scopes also doesn't appear on the arsenal.
