I've installed 2.9, New Dawn 1.71 Custom setup.

Whenever I play a game, if I cancel/change what I'm researching, the game crashes. Any idea what's going on?

Known Bug, is fixed for next patch.

To quote Afforess

"To All;

I can confirm the issue with clicking on the research bar, and have already fixed it. Expect a quick release (1.72; due to save compatibility) by wend. "

What's the exact problem? Would map size, number of civs, barbs, have any bearing on this? Is this for the 1.72 to fix? Just completely lost when it comes to more complicated anomalies.

Nothing you would care to understand. Basically, when you click on the research bar, you removed your current research; which means you are research no techs. No Tech is a special value in the game, -1. I wrote some changes for Civ Fuehrer so he could make Techs Require buildings before they could be researched, but when you check those new buildings against -1, the game CTD's.

Told you, I knew you wouldn't care. ;)

If it's none of my business (which it obviously isn't), then of course I wouldn't have known. I suppose all I care about is just enjoying this as best as I can, nothing's perfect. We've all got other things to do, this'll take its time.
