Looks like I'll have to redo the verbal system, then (not that there's all that much to redo). Do you have any idea why this pattern exists?
I can't say for sure, but in general objects tend to be more tightly bound to the verb than subjects are. One example: there are lots of verb-object idioms, but (transitive) subject-verb idioms are rare. (I think this is true even in languages in which you might otherwise think there's no verb phrase, such as VSO languages, but I don't remember details.)
In Chomskyan treatments, object agreement gets handled closer to the verb, within the extended verbal projection, whereas subject agreement gets handled around IP (I hope I've got the lingo right), and at least a lot of the time affixes associated with positions lower in the clause end up closer to the verb (that's Baker's Mirror Principle).
I admit that I've never felt I understood how it could be true both that you can't get object agreement without subject agreement and that object agreement markers end up closer to the verb. Shouldn't there be a stage in the development of polypersonal agreement where you've only got object agreement?
You can get at least apparent exceptions if your object "agreement" markers are actually clitics. I don't know about other exceptions.
