It was pretty much a wash so I didn't bother calling BA to change it.
I have had a smilar thing happen to me more than once. MFU (at time of booking) from WT+ to CW with a UK domestic which should have generated 20+75+75+20 and ended up generating 0+120+120+0 with the domestics showing ineligible. I was too chicken to complain about the 0s in case they took away the 120s.
