Squids no longer are affected by water currents like they were in 1.7.10 and before.

This squid farm and others alike worked in the before versions, however now they do not due to the squid being resistant to the water currents.

The squid look like they are bugging out as they swim in water currents, leading me to think this is not an intended feature.

This happens both in single player and also on a server I play (both in the snapshot)
