As you might know, as of 1.0.3.2 certain projectiles (Fox's lasers, Falco's lasers, Isaac's side b, etc.) Are unable to break targets for some reason unlike the previous version of Beta. This makes in impossible to beat records on target for certain characters In 1.0.3.2.

With that said, would it be okay to use a previous version of Beta like 1.0.2 for target test to submit records until another patch fixes this problem?

I don't think there's any problem with that
