Assault class misses target?

I've had two instances that I know of with Rosita shooting at a walker and bullets go right through it. The first time I wasn't sure, this time I know it's a bug. She was on point facing a walker, no space between them, Daryl behind. Daryl unleashes his critical shot and dropped the walker to 7 health points, Rosita fires and all bullets miss, walker attacks Rosita and she dies. Anyone have this issue?
