Problem with contacts

[albertlee60]

I am encountering problems with contacts since updating Adium from 1.4 to various versions of 1.5. Several contacts - all on MSN and sharing the same office - have merged and became one single contact. As a result, often I thought I was massaging Contact A when in fact I was sending massages wrongly to Contact B. The only way for me to resolve this issue is to revert to an older version of 1.4.4. Surely there must be a better way to resolve this? I am running a OSX 10.8.2 on a Mac Mini, a MacBook Air and a MacBook Pro. The problem is the same across all three platforms. Any suggestion?

So the metacontact actually changes if you downgrade to 1.4.4?

Do you have the contacts listed under one name in Adress Book?

David, my contacts are organised in different groups, such as friends, family and colleagues, etc. Yes, effectively some of the meta-contacts changed (for the worse) every time I upgraded to a 1.5 version. Then they would change and "heal" when I downgraded to 1.4.4.
