Did the Prospector item break in last update. I've played a few games since update with prospector and havn't seen any asteroid indicate it has minerals in it.
It shouldn't have. The crash was just a typo in the archive code, so nothing changed with functionality of the items. Maybe you've just been unlucky. I will check it though.
It's still working. If it's a previous run from before the patch it's possible something has gone wrong though. Dropping it and collecting it again should fix it though.
Hmm. I've played about 10 games after the patch and Prospector hasn't highlighted any asteroids. Randomly shooting asteroids I have gotten minerals out of them that the prospector had not marked.
