[Open Assets] Riviera Pack 1.2

Solidified some sneaky fences and spruced up the temple roof a bit. (thanks for the catch AnimeSonic)

Turned out someone else did use that slot already. Whoops.

Now it's two maps.

Made some changes to improve visibility in Lacrima Castle and hopefully make the roof transfer section less weird, but I'm sure it could still use some improvements . Heaven's Gate is brand new and probably full of even weirder things for everyone to enjoy. And likely also uses a map slot someone else is now using because I haven't checked the list in the last two years.
