[07:15:54] [Server thread/ERROR] [AncientWarfare/AncientWarfareStructure]: Could not locate biome: desert oil field while registering template: desert_tower for world generation.

This error shows up on my server log and my server possibly isnt starting up because of it!

This error doesn't stop a server from lauching properly.
The problem should be located way under that line.

closing

This error is still showing in SMP logs... I presume I'm not using the right mod to have it??

Version: ancientwarfare-1.12.2-2.4.37
Forge: forge1.12.2-14.23.1.2555

reopening to check what's happening with this in 1.12

closing, this is now fixed in 1.12
