# BUGS

A few files from TH12 and TH13 contain overlapping entries with different formats. Dumping and recreating these archives will not result in the same archives. The affected pixels seem to all have 0 for alpha though.
One of the scripts in TH95's front.anm lack a sentinel instruction. Dumping and recreating this archive will add a sentinel instruction.

# SECURITY CONSIDERATIONS

File names may not be properly sanitized when extracting. Furthermode, invalid data may not be properly handled. Do not operate on untrusted files.
