Yeah this is definitely the thing stated above, it's a bit weird and I should make it be more visual but nothing alarming; thank you for reporting it just incase though.
I did do two giant advanced meth sells for a couple billion each. I noticed that right before I swapped jobs for the night that my last adv printer sell was normal.
I believe this is because you are 'backed up' in criminal crate money, did you do a big sell recently like fireworks or something? This will give you a criminal crate every sell until your criminal crate 'bucket' is at less than $150m.
