did a little testing, as im currently playing and had the issue again. this might not answer it, but i have 2 ideas from what i just did. had another big report i tried filing multiple times, kept messing up. i dwindled down charges until it worked, and either A) Burglary Tools charge is bugged, or B) it has to do with too many characters in the charges section. 3 felonies, and all have long names, so im wondering if that is the issue, that it basically goes off page and glitches the report. if not, since Burglary Tools was the last charge i removed before it worked, then that charge (and maybe a couple others?) are bugged.
having the same issue myself. it seems like it happens mostly when i get a big arrest report, say more then 4 charges? it doesnt seem to happen to cases where the person has just a DUI, or just a shoplifting charge, but when i try and make a big case out of a felony evasion with multiple drug types, illegal possession of weapons, etc etc... thats when i get a blank report. or double reports (i can get a pic if needed). arrested a guy, auto case for DUI, i search vehicle and him, find a couple other illegal items, make another case on felony charges. DUI case has results, felony case is blank.
