Sketchy Minefields

[treadasaurusrex]

An odd situation has arisen while setting up a scenario.

I am playing an online opponent in An Army At Dawn scenario with minefields with no issues to report.

Now, I am playing another online opponent in the same game set -- but a different scenario (#38 El Guettar). This time, the minefield markers won't show up in the Random Counter tab so that they may be placed on the battle map. Tried doing this in solitaire mode and as both sides, as well. Same result - no minefields visible to select - just an empty grey box. Tried deleting and then re-installing the core data minefields extension a couple of times and failed both times.

 Am I doing something wrong, or forgetting a key step in the process?
