"Will only count wall bounces even if PROJECTILE_FLAG_NOENEMYHITS is included in the PROJ_WORKSLIKE flag"
Hmm... I don't have that flag, and still PROJ_BOUNCES works.
There is a default number of bounces when there is no PROJ_BOUNCER or if it set to 0 and negative numbers. I think the default number is 3, or maybe it can be NUMFREEZEBOUNCES?
