Thanks for that. I did complete the level again, and even though the inhibitors visually appeared again, the achievement came through once I finished the level

I restarted the level, reached the point where all the inhibitors had been destroyed, (and heard the message telling me so) saved the game, continued, and saved a separate file for the continuation. In both instances, all except the last destroyed inhibitor have reappeared again, as I mentioned originally. I would be glad to send you the save game files, one or both, if you tell me how to identify them, and where to find them. I also need to know how to access the log file.

Thanks for your help.

I'll do what I can. What output log?--What and where is it? As to the save file, it's been overwritten at least six times as I replayed the game.

Windows 10 Home 64 bit (HP 500-164 system)

amd a8-6500 apu with radeon HD graphics 3.5 gh (but I put in a geforce gt 730)

installed ram 32.0 gb

The mouse won't go into scrilling mode, it just rotates, even if i repeatedly click the middle mouse button, or zoom in or out, or use the keyboard scroll keys. the view just changes from straight down to the standard view, not allowing me to move around the map
