In some quests (I tested bs1st (the 2.10.2 one) and a new quest), the arrows don't fly across the screen when used - they merely 'stop' in front of Link, and he can't fire another one until an enemy walks in to the arrow point.
Strange arrow-firing behavior (b278)
Probably due to the block arrow combo stuff I was messing with. I'll check it out.
Fixed. The power for the small bow was defaulting to 0 instead of 1. This will automatically correct for older quests. If you've saved your quest in a recent beta (probably anything since 254, maybe earlier), you will have to edit the power of the small bow manually.
