Oops, it seems that roborumble client cannot download your bot, from all over the world. Maybe dropbox set the restriction, or there may be some bug in any of the ends.
And after downloading your bot manually, roborumble client throws exception and exits completely.
Best I can tell is something happened during upload/download of this version. I've downgraded to 1.9.2.5 and 0.02 works just fine locally. I'll do some more testing and then maybe a version bump before I try again.
Maybe my manually curled version is just an empty file, since without -L it wouldn’t follow redirect and leave blank. If that’s the case, I would put 0.02 back since it’s totally fine.
