Coding Help npc can't enter custom location

[goron]

I'm maintaining the Solarium Spa mod that adds a custom greenhouse to the game that can be accessed through the Bathhouse Entry (mod page here for reference). The mod changes Linus's schedule so that he visits the Solarium in the fall and winter. However, upon entering the Bathhouse, Linus gets stuck and doesn't go to the Solarium. I'm wondering if there's an issue with how I've set up the map edit that adds a warp to the Bathhouse entry that makes it unusable for Linus (it works fine for the player).
Here is the tmx file code for the bathhouse entry warp:
