A bug that has now ended three of my solo flawless attempts in duality…two of which were at final boss…
If the bells are shot once to trigger the bell and then shot again immediately before it swaps you to the next realm, the bells will wipe you. May not happen 100% of the time, but often enough to wipe all my runs. Each time it has happened, I have shot the bell with a couple more rounds thinking I did not trigger it, but this ended up wiping me.
