I have a problem on my server. When a hunter captures a pet the hunter lose the pet when on relogg. So... Something like each time the hunter loggs on he needs to catch hes new pet. The old pet can't be summoned or called and its not at the stable master.
Oh.. I got another problem with pets also (both hunter and warlock pets). When you summon them I think they get to the table npc_spawns because they get a spawn location atleast.
+Rep to the one that posts a solution.
