Slitherine

I have installed Fortified Line Leaders version 1.4 (the latest I believe).
While watching my opponent's replay a window popped up saying

MISSING IDS IMMOBILIZED TRACK

Question: Is it I that is missing something or is that a problem with my opponent's version?

Thank you

This is a know bug, it's irrelevant on play.
The missing string will be fixed in the next version.
Sorry for the inconvenience.
