I've also noticed several times now that when I knock down all the little deadpool targets for mini deadpool MB all the targets reset when the light turns to green (the mode is ready). This doesn't happen on any of the other DP's I've played. Happens whether all 3 are knocked down or just 2 out of the 3. I'll have to investigate why on that one.
I thought it may have been the issue that was linked in the first page but the targets work perfectly in test mode and they will even drop in ball search (got a ball stuck behind them once already) so I don't think it's the drop coil bracket issue.
