Hi,
I recently installed the omnicomrpession mod, and, sicne it seems to be a dependencie, the omnilib mod.
However, on startup I got this error:

Omnimatter_compression/data-final-fixes.lua:10:omnimatter_compression/prototypes/compress-ores.lua:34:attempt to perform a arithmetic on field 'maximum' (a nil value)

When I looked into the files it seems those values/liens are in there to work with the other omni mods which I don't use, and when I deleted the lien in question the mod does start up and works just fine so far. However, I'm not sure if that won#t break anything further down the road.
