Confirmed, if you select a research item before reprogramming it doesn't crash. tnx.

I've looked in the "C:\Program Files (x86)\Steam\steamapps\account name\darwinia" directory, nothing there either. If you show me how I can debug darwinia I'll be happy to try and debug.

Sorry, no blackbox file. Atleast I've looked in the saved games folder under mods and users and it's not there. Maybe it's stored somewhere else?

I've tried your mod (looks very promissing) but it always crashes on the first map for me. As soon as I reprogram a building with the engineer (doesn't matter which, radar dish or trunkport) it crashes. I have the steam version and I'm running Windows 7 64bit.
