LE, this table does not appear to be listed in the table_versions list. Scatman was comparing his spawn_ground to mine, and his is missing the collection_skill field completely. I went to see what version my table was, but it's not in there.
Just FYI.

Oops, must have been an oversight on my part. Be sure to back the table up, because when it grabs the table from the update server it will drop it before it creates it. Same thing goes for the groundspawn_* tables.
