Did that mod add any fields to the *_TOPICS table? If so, they'll need to be added to the *_A_TOPICS table as well.

The MOD installation did not seem to add the fields to the archive table, nor does it transfer the T_MEMVIEWED values when the topic is archived - Perhaps some ideas for the next update?
I've noticed this with a handful of mods, they add fields to TOPICS and REPLY without adding the corresponding fields to A_TOPICS and A_REPLY. The way I undersytand the archiving process, it will copy all fields to the corresponding fields in the archive tables (if they exist) without having to make any additional edits. I've added a few fields to these tables on MeTV without the need to specify that they get copied over when archiving.
