Odd Seas in TM 1.6?

[banjo]

Has anyone else noticed odd quilt like seas (i.e. repetitive pattern) in TM 1.6 that weren't there in 1.4? Part of the living sea mod or something?

And while I am at it ( lol ) can some modder activate the 'opening tube x' voice messages?

Thanks.

Part of enviromental mod, and doubtful.
