Fix final boss maze switch placement (1.0.1961) — Dungeon Looter Steam update #107025

1.0.1961 Fix final boss' maze switch minigame where switch could spawn outside boundary. Maze Switch This could happen in very high difficulty setting as more switches will spawn. It has very small chance to pick the "fallback" spawn location when the code failed to find the ground, thus it spawn in the center of the room, which specific room like in the screenshot has hollow in the center, making switch unreachable and make the game impossible. The new version will stop using "center of the room" as fallback position and try to place it in the starting room instead.
