I know about the following respawn types, and how to use them.
The last one, Side, baffles me. It acts exactly like group. Is there a difference, or is it in there just for flavor?
None - No Respawning
Bird - Respawn as Seagull (Default)
Instant - Respawn at last location (new unit)
Base - Respawn at side's base marker (new unit)
Group - Respawn as another member of same group
Side -
