1st Scenario - Graphic Bug??

Not sure if this is a bug or not. Was playing the 1st scenario, irrigating along just fine. Saved the game and quit.

Next time I logged on, about 2/3rds of the irrigation squares had...changed. They now had a silvery kind of tube/vein look to them rather then the standard white-on-greenish irrigation effect. If this new appearance was supposed to represent some new era-specific kind of irrigation, I have no idea what they were supposed to represent.

Didn't seem to affect production. As I continued to irrigate squares, I got the same effect at about a 2/3rds ratio.

I didn't do anything with the .SAV file between sessions.

If this is a bug, let me know and I can post .SAV file and screen graphic.

If not, never mind. I'm just curious to know what the heck it is that I'm supposed to be looking at!

Thanks!

Do you have a screenshot? Can it be reproduced? It sounds like a normal low-memory type bug where one graphic gets altered. Most likely, that's what it is. It isn't a bug, but hardware that's affecting it. Also, write the steps to reproduce it, and upload the all important save file.
