Had this happen twice now - checked my merc window, and discovered that one of my mercs was replaced with an exact copy (class, rank, name) of another merc. e.g. my mercs were Damage Caster, Healer, Tank, Melee Damage. They are now: Damage Caster, Healer, Damage Caster, Melee Damage. The second Damage Caster is duplicate of the first, even down to the name. I *think* this is happening on zoning - today I zoned from EW to GD - before I zoned, I did not have a merc out - my current was was the Tank (suspended). When I zoned into GD, I realised the Caster merc was out, even though I had not unsuspended her. I think this is when the Tank got replaced with the Caster.
