i didn't say anything about matching spawngroupID. it's the 'version' field in the spawn2 table you need to have correct when creating the instance.
Code:
mysql> describe spawn2;
+--------------+-----------------------+------+-----+----------+----------------+
| Field | Type | Null | Key | Default | Extra |
+--------------+-----------------------+------+-----+----------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| spawngroupID | int(11) | NO | | 0 | |
| zone | varchar(32) | YES | MUL | NULL | |
| version | smallint(5) unsigned | NO | | 0 | |
| x | float(14,6) | NO | | 0.000000 | |
| y | float(14,6) | NO | | 0.000000 | |
| z | float(14,6) | NO | | 0.000000 | |
| heading | float(14,6) | NO | | 0.000000 | |
| respawntime | int(11) | NO | | 0 | |
| variance | int(11) | NO | | 0 | |
| pathgrid | int(10) | NO | | 0 | |
| _condition | mediumint(8) unsigned | NO | | 0 | |
| cond_value | mediumint(9) | NO | | 1 | |
| enabled | tinyint(3) unsigned | NO | | 1 | |
| animation | tinyint(3) unsigned | NO | | 0 | |

if you want to create an instance of cshome where the zone is populated with what is in the database by default, use 0 as the version in plugin::SendToInstance() instead of 1.
this is what spawn2 table entries look like for cshome:
Code:
mysql> select id, zone, version, spawngroupID, enabled from spawn2 where zone = 'cshome';

note that all of the spawn2 entries have a version number of 0. that indicates the version of the zone those spawn2 entries are valid for. you can have multiple configurations (versions) of the same zone, each with different spawns (as well as quest scripts).
