[Silvers]

Alternating start up... so they're missing only from the first map after boot? Or subsequent maps too? If listen server that could be a reason, most my plugins (and others) don't support listen servers.

Edit: Could very well be the "*_random" cvars added to most my spawner plugins. Set to -1 to spawn all at once instead of it randomly selecting some to spawn.

Edit2: It was the "*_random" cvars.
