Editing a custom syntax didn't work until I made a new syntax file for it

[Flurrywinde]

What steps will reproduce the bug?

1. Add a new syntax (details in this issue) called ChoiceScript.
2. Modify it.

What happens?

The modification doesn't work. Bat's output doesn't reflect the modifications to the syntax file, but it correctly applies the original syntax rules.

What did you expect to happen instead?

Bat's output should reflect the changes to the syntax file, and it does if I make another new syntax, nearly identical to the first:

How did you install bat?

System Config file

Could not read contents of '/etc/bat/config': No such file or directory (os error 2).

Config file

# This is `bat`s configuration file. Each line either contains a comment or
# a command-line option that you want to pass to `bat` by default. You can
# run `bat --help` to get a list of all possible configuration options.

# Specify desired highlighting theme (e.g. "TwoDark"). Run `bat --list-themes`
# for a list of all available themes
#--theme="TwoDark"

# Enable this to use italic text on the terminal. This is not supported on all
# terminal emulators (like tmux, by default):
#--italic-text=always

# Uncomment the following line to disable automatic paging:
#--paging=never

# Uncomment the following line if you are using less version >= 551 and want to
# enable mouse scrolling support in `bat` when running inside tmux. This might
# disable text selection, unless you press shift.
#--pager="less --RAW-CONTROL-CHARS --quit-if-one-screen --mouse"

# Syntax mappings: map a certain filename pattern to a language.
#   Example 1: use the C++ syntax for Arduino .ino files
#   Example 2: Use ".gitignore"-style highlighting for ".ignore" files
#--map-syntax "*.ino:C++"
#--map-syntax ".ignore:Git Ignore"
