Scourge of War Boards

I have encountered a bug repeatedly where artillery under my control reports incorrect ranges for various units. That is, if I select e.g. the 151st Pennsylvania, it will display a range with 7 or 8 digits, rather than the correct range. However, the “correct” unit range is listed as an additional target. The artillery cannot be switched to another target once this bug occurs, and will continue to display the “no valid targets in weapon range” message.

Has anyone else encountered this/implemented a fix?

Don't recall this issue. Attach a save with the unit selected that's displaying the ridiculous ranges and we'll check it out. Disable any mods while acquiring this save. Thanks for the report.
