Maybe because you are using the wrong argument?

And, addrid is somewhat confusing for me, in your place I would do a query_sql where char `last_map` = x, using SQL function RANDOM to randomize the result.

Save in a char/account permanent variable the time he first spoke with the npc. And add a check too see if (now) > ( first_spoke + 60 * 60 * 24 ) { // repeat quest }

I don't remember the command that return unix time, check the scripts doc.

I have the same error, but only on a specific point of the map. Same hexed, already remade the mapcache.
 
The problem is the gat,  have no clue how to fix it, nor why it's bugged

I'll help you because you have great taste for bands

go to conf/battle/misc.conf
 
// Allow autotrade only in maps with autotrade flag? // Set this to "no" to allow autotrade where no "autotrade" mapflag is set. // Set this to "yes" to only allow autotrade on maps with "autotrade" mapflag. at_mapflag:    Set it to yes, than put a mapflag where you want
