Column markers are in the Infantry tab of each side's Pieces window. This module is pretty awful, it could use a ton of work--and I don't even know how the game is played.
I hadn't looked at the mod until now and there are a few issues I already see:
• none of the starting position markers are set-up on the board
• the "opaque cup" should already be populated with the city/town markers
• there's no player area/board to place your airgroups (open information) & initial city/town markers
• no area to place counters to simulate counter limits
• area for operation pack is buggy & you can't stack cards on top of each other
I'll be back for good on August 5th. Let me know if the VASSAL mod is good enough to play, I'd be totally down for it. I'll also be restarting our GCACW campaign then, Kingput.
