Squids dont spawn naturally but should.

We realized that squids don't spawn on the map some time ago but thought this was due to biomes.
As a workaround #98 was added.

Turns out Biome restrictions did not affect squid spawning in 1.12.2.

RGBPixl covers the issue and possible causes in his video pretty well:

Maybe it's among the ton of features that quark adds?
