Very annoying province defence bug...help please?

[Nerfix]

Hey, while testing Sar Elad mod Agrajag noticed that the province defence is bugged. so it's my responsibility to fix it, but I have no idea what's wrong.

Code is here:

-- Province Defence --

#defcom1 2975
#defcom2 2985

#defunit1 2998
#defunit1b 2997

#defunit2 2991
#defunit2b 2994

#defmult1 20
#defmult1b 20

#defmult2 20
#defmult2b 20

It seems that only defunit2b is working out of all those. Or perhaps it was defunit2...gah...
