[ FF7 ] Custom music not being called for [battle_ID#]

[futcharist]

When attempting to load custom music for specific encounters using [bat_xxx], config instructions are bypassed while engine searches for [bat_0] instead. Further lookup by [bat_fieldID] and [scene_xxx] is working as intended, so far only [bat_xxx] seems to be affected. Was working in previous version of FFNx.

To Reproduce:
Install ReMusic in latest Tsunamods version of 7H. It includes a custom config.toml that will supersede whatever you have set in your FFNx config folders.

Set music to VGMStream in Driver Settings

1. Go to Train Graveyard
2. Encounter either Eligor in north graveyard field or 3 ghosts encounter in south
3. Note in trace log that neither custom track for either encounter plays, only either the default graveyard music or the default battle track.

This same behavior manifests itself on other fields/other encounters with specific track selections, IE Sample H0512 in Shinra Building. It can be worked around by configuring the encounter field to call the desired custom track, but has assorted undesirable effects such as triggering the same track for any other music call made on that field, IE after the battle ends and field resumes.
