Yes, this event is definitely bugged. Saw reports of people saying it only gave them 8 attempts instead of the advertised 9. Similar to the bug with the same event we saw in the Boss promo from OD.
This was a glitch last year too. Pretty disappointing that they didn't fix it, simple math...
Don’t know if there’s a thread about this already but on Stage 6 of the Training Camp Master series, the throw for 6 TDs on 9 Attempts ends after 3 non-TDs even though you still have 6 attempts left.
