you have to add support for it in this function:

Code:
def customproperties(o):
    
    f1=f2=f3=f4=f5=f6=f7=f8 = 0
    polygon = 1
    s1=s2=s3=s4=s5=s6=s7=s8=s9=s10=s11=s12=s13=s14=s15=s16=s17=s18=s19=s20 = 0
    action = "ndef"
    material = "ndef"
    substitute = None
    
    for p in o.getAllProperties():
        if p.getType() == "BOOL":
            if p.getName() == "flag1": f1 = p.getData()
            if p.getName() == "flag2": f2 = p.getData()
            if p.getName() == "flag3": f3 = p.getData()
            if p.getName() == "flag4": f4 = p.getData()
            if p.getName() == "flag5": f5 = p.getData()
            if p.getName() == "flag6": f6 = p.getData()
            if p.getName() == "flag7": f7 = p.getData()
            if p.getName() == "flag8": f8 = p.getData()
            if p.getName() == "polygon": polygon = p.getData()
        if p.getType() == "FLOAT":
            if p.getName() == "skill1": s1 = p.getData()
            if p.getName() == "skill2": s2 = p.getData()
            if p.getName() == "skill3": s3 = p.getData()
            if p.getName() == "skill4": s4 = p.getData()
            if p.getName() == "skill5": s5 = p.getData()
            if p.getName() == "skill6": s6 = p.getData()
            if p.getName() == "skill7": s7 = p.getData()
            if p.getName() == "skill8": s8 = p.getData()
            if p.getName() == "skill9": s9 = p.getData()
            if p.getName() == "skill10": s10 = p.getData()
            if p.getName() == "skill11": s11 = p.getData()
            if p.getName() == "skill12": s12 = p.getData()
            if p.getName() == "skill13": s13 = p.getData()
            if p.getName() == "skill14": s14 = p.getData()
            if p.getName() == "skill15": s15 = p.getData()
            if p.getName() == "skill16": s16 = p.getData()
            if p.getName() == "skill17": s17 = p.getData()
            if p.getName() == "skill18": s18 = p.getData()
            if p.getName() == "skill19": s19 = p.getData()
            if p.getName() == "skill20": s20 = p.getData()
        if p.getType() == "STRING":
            if p.getName() == "action": action = p.getData()
            if p.getName() == "material": material = p.getData()
            if p.getName() == "substitute": substitute = p.getData()
            
    skills = (s1,s2,s3,s4,s5,s6,s7,s8,s9,s10,s11,s12,s13,s14,s15,s16,s17,s18,s19,s20)
    flags = (0,0,0,0,0,polygon,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,f1,f2,f3,f4,f5,f6,f7,f8)
    return action, skills, flags, material, substitute


it's easy. the only problem is figuring out which of the zeros in flags = (...) is the passable flag and i don't have time for that now. you have to save some simple test $$m from wed.
