Well, if you punch those numbers into a caclulator without rounding, you get a base corruption of 25 + 9*4 = 61. Deduce 15% of that and you get 61 * 85% = 51.85. Applying that to 11 trade, you'd get 11 * (100 - 51.85)% = 11 * 48.15% = 5.2965 trade left. If we'd rounded before, we'd have gotten 11 * ...

Are you sure the waste by distance calculation uses pythagorean distance? If we use shortest path, that's only 18, which would lead to a corruption of 97 (which is in percent, according to README.effects). 14 * 97% yields 13.58, which (I would assume) is truncated to 13. I would like to mention, tho...

No, not currently. In Freeciv 3.1, there will be a voodoo method using lua script, but until then, you're out of luck.

Veteran_Build has always worked with UnitClass requirements; otherwise the whole idea of having separate barracks, port facility and airport would've never worked. To be honest, I wouldn't look at the wiki for things like that (that page is outdated anyways), but instead look at README.effects, and ...

You could start the server with verbose logging, i.e. "freeciv-server -d 3", and then, when the error occurs, look at what came before (presumably attempting to send something to the client).

Also, I believe the "negated" (and then "present") aren't supposed to be something additional, but a way to generalize and abstract the requirements system, which makes both it and anything dealing with it (such as AI) clearer and less error-prone. I think it is clear enough tha...

Adding more complex effect requirement formulae probably wouldn't affect computation time too much, but it would make it significantly harder for AI to understand them. Also, I believe the "negated" (and then "present") aren't supposed to be something additional, but a way to gen...

Yes. Different effects of the same type always add up, and the Upgrade_Unit effect upgrades a number of obsolete units equal to the sum of all active effects per turn (as you could have actually figured out yourself from README.effects).

You get multiple units upgraded for free every turn. This has been used in e.g. the multiplayer ruleset.

For big cities, opening the Cities screen (F4 in the gtk client) is probably more sensible anyhow. All I need is just a 'few' more columns. Like what? I can't really think of anything missing right now. Depending on whether you like multiple things in a single column, you can have between 24 and 34...
