This may only affect skytemple-rust.

For unknown reasons, when trying to import portraits from separate files, some conditions may throw this error:

PanicException: range end index 48 out of range for slice of length 45
  File "module\portrait\controller\portrait.py", line 153, in on_separate_import_activate

This has been reported 61 times via Sentry with the latest version being 1.5.4.

We just got a report for the 1.6.0 final RC that this also happens in the Randomizer sometimes. There may be specific portraits that cause this.
