    if(!g_ShinobiPowers[id])
    {
        g_JumpPower[id] = 0
        g_TouchingIsGood[id] = 0
        g_fallProtection[id] = 0
        
        entity_set_float(id, EV_FL_gravity, 1.0)
        entity_set_int(id, EV_INT_renderfx, kRenderFxNone)
        entity_set_int(id, EV_INT_rendermode, kRenderNormal)
    }

I see this as a potential bug, I haven't tested. This is found in the posthink forward. With this, it seems as if their gravity (and render stuff) will always be set to normal, no matter other heros they have which causes great conflict .
