Last update works perfectly fine. I only have a few suggestions for future releases. I tried to adjust the script myself, but it wouldn't open in QuickEdit Pro or Wordpad.
First suggestion is to set the value of the packs (currently -100.000 coins) to the users preference. That way the user can change it to a number they see fit (maybe add a warning to not go beyond 100.000 in order to prevent a ban).
Second suggestion is to add an option to do live SBC infinitely.
Third suggestion is to increase the number of packs in "my packs". This could be really useful for FUT Champs packs.
I'm not sure what is possible and what you already have planned, but I think these suggestions could be an improvement for your script.
Really like it thus far, so keep up the good work! Cheers.
