That makes perfect sense, thank you much! Only part I don't get is Super Dune didn't / couldn't fix? I'll patch my original install to v1.07 immediately. 8) All the Best, Roy ---Update--- Wow, even knowing that... that scenario is nearly impossible to complete! Had to redo three times to beat it. Can't harvest above with Merc Devastator, below Merc Siege, so constantly babysitting the harvester to not trigger Siege; meanwhile Devastator lays waste to your troops and base. Level has to be finished in 8mins or less, otherwise you are toast. Whoever designed that level deserves some unkind words!!!
