Ladder Shuffle (Archipelago)

Several individual ladders and groups of ladders have been turned into items, requiring you to find them before they can be used. This blocks off access to many different areas in the game, adding a new layer of progression to the randomizer.
Construction signs will be scattered all around the world, and interacting with them will tell you the name of the ladder item needed to unlock the ladder. In many cases, multiple ladders are tied to the same item.
This option can currently only be enabled through Archipelago, so if you wish to play with it solo you will have to generate a solo Archipelago game with it for now. It may get added as a standalone option for single player in a future update.
Currently, the first steps mailbox hint does not account for ladders being in your way, but is still accurate for when you do gain access to the specified area.

Bugfixes and Other Changes

Added support for connection plando for entrance rando in Archipelago
A custom seed can be used for determining the entrances in entrance rando in Archipelago by changing the value in the YAML for entrance_rando to any string besides 'true', 'false', or '0'
Fixed a crash that would sometimes occur when loading into the Title Screen.
Corrected the amount of holy cross checks the ending screen says there are (now says 35 instead of 41).
The money spawning animation is now skipped if skip item popups is turned on.
Starting a New Game on Archipelago will now always re-process any previously received items (it used to require disconnecting and reconnecting if done in the same session after loading another file).
