Then we needs a save before Ringo closes our quest (i dunno if it will works when he denies out help and quest fails)
Luckily, i’v got one of the autosaves
I stepped outside of gas station
Opened console and used commands below
resetquest 00104eae – resets quest
sqs 00104eae – to see stages of that quest i can use
setstage 00104eae 5 – quest starting stage
setstage 00104eae 10 – Ringo now should ask you about Sunny Smiles
after that, you should do quest as always
i gathered whole town without a problem and killed all bandits
If Ringo keeps saying about some bandits to look – you need to find Cobbs corpse, select it in console, type resurrect and kill him again
After that, quest should be complete and Ringo will reward you with caps
Hope it helps! Happy New Year everybody!
