Is there an existing issue for this?

Observed behaviour

When trading with friendly Warlocks or Battlemages (I assume it happens with Sages too), the friendly casters do not operate the way that normal Wizard traders do:

1. When a trade becomes unavailable, it does not refresh and become available after time (or due to other trades)
2. The default trade often comes up as a non-standard spellbook (below you can see it's a mowzie mob spellpack spellbook), but the trade won't accept either a spellbook from that spellpack not a normal spellbook as a trade.

Expected behaviour

I expected trades to work like they do with normal friendly Wizards.

I expected that I would be able to trade any wizard spellbook (from electroblob or one of the spellpacks affiliated with it) as a base trade.

Steps to reproduce

1. Join a Server
2. Find a friendly Battlemage, Warlock (or perhaps Sage)
3. Notice how the trades may operate.
