Cooking Map Extension

Just need some clarification on what activity i should see in the .bat logs when a map extension is/has cooking/cooked, as it appears unresponsive.

Current been cooking for 8 hours, and log appears stuck on “full gc”
.bat log’s last entry was :Saving map ‘Ragnarok_Namewall_Temple’ took 1.436

Just wondering if this is all part of the process, do i leave it chill, or have i done borked somewhere?

Cooking a map and loading a map for the first time takes hours and hours depending on the cpu. It’s normal. My first cook of a map took about 6-8 hours.
