Upgrading

[High Lord J]

What is required to uprade a unit?

Sometimes I can updgrade and sometimes i can't. In my current game as the indians I have a bunch of warriors ready to become swordsmen and I have researched iron working and have it in the resource box. What else do I need?

Barracks in the same city the troops are in.

Yup, you need a barracks in the same city as the warriors to upgrade.

Although not directly applicable to your situation (warriors - swordsmen), I thought I'd also let people know that I encountered an upgrade problem that really caught me off guard. I happened to fall way behind the various AI civs and found myself with neither saltpeter nor the military strength to go take some saltpeter. No problem, I thought, I'll play very, very nice until Nationalism, and upgrade to riflemen then (skipping over musketmen, which require saltpeter; riflemen do not). Built a bunch of pikemen in the meantime, both as a deterrant and as an "upgrade force" for when I hit Nationalism. Discovered Nationalism; went to upgrade; could not upgrade one single pikeman! until, of course, I sold my first-born for a supply of saltpeter -- then I could upgrade straight to riflemen. Tells me that the upgrade algorithm clearly looks at steps: i.e., spearman to infantry is actually spearman to pikeman, pikeman to musketman, musketman to rifleman, rifleman to infantry; which means you effectively need iron, saltpeter, and rubber to upgrade that lowly spearman!

Also, Mac versions seem to have a bug when upgrading to a UU.

Catt, the new Vel.

I don't know why or how, but you seem to be discovering new aspects of the game on an ongoing basis.

I've got a new one too: GL generation is not as simple as we thought. I screwed up moving an elite-leader Cav (again, that's an elite who has already created a GL), and re-loaded. I figured, what the heck, and used an old elite Swordsman to generate the GL, planning to disband him afterwards... NO GL!!!! I tested this 3 times... the Cav creates the GL, the Swordsman does not!

You two are little gemstones.
I'll give 1000 gpt and Synthetic Materials for Theseus and Catt as MPPs in MP
