Pre-completed Dungeons Mode Bug with Multiworld

[tanjo3]

We tried to roll a 3-player multiworld seed with 3 pre-completed dungeons here: https://ootrandomizer.com/seed/get?id=1759287

So, we'd expect to start with 4 dungeon rewards, as indicated in the spoiler log's playthrough. However, when you go into game, we all started with 7 dungeon rewards instead. This happened to all 3 players in the multiworld.

As an example, here's Player 1. Per the spoiler log, they should start with the Kokiri Emerald, Zora Sapphire, and Water and Spirit Medallions. However, they clearly also started with Goron Ruby, and Light and Fire Medallions.

We were able to reproduce the bug on Dev-Rob: https://ootrandomizer.com/seed/get?id=1759319
