If set in new game menu "island" option on terrain setting tab, "water" setting changes to "island size", where "coverage" is blocked on 100%. Then if create game or exit back to main menu, game remembers "island" choose. Then if open new game menu again on terrain tab will be "island", but also "water" instead of "island size" and "coverage" is not blocked. Trackbars works as in "island" mode, but setting "coverage" of "water" to "only in starting area" makes non-island map.
Setting "island" to "normal" and back, recovers "island size" text instead "water" and blocks "coverage" in 100%.
