Got a few issues, Nighty, and i dunno if they're bugs or what.
First of all, i do not use the moddir, but fully replaced the original files with your mod (i dunno if this shows any difference ingame). playing A World Tumbling as USA:
1. I wasn't able to upgrade units. Every pre-war stuff i sent to upgrade came back as pre-war stuff.
2. There was 1 fleet in which i coouldn't select individual ships because the slidebar was crazy. I found that there was 2 ships with the same name (a convoy) and that might be causing the weirdness. The only way to avoid it was to create a new unit and move away everything but the duplicated boat.
3. Paratroopers are waaaaay too downgraded. I know about the paratrooper exploit, but i think the workaround was too excesive, imho, although it is necessary. Btw, after getting the 82nd Airborne, i get the 101st, then the 101st again, and again and again (i know that it was already reported... gotta check unitnames.csv mod thread).
4. The game crashes (screen freezes) at the same time sometime during 1943. Maybe it has something to do with the US elections event or some other thing... i dunno.
Beside it, i was really enjoying the mod! Now i think that i'll reinstall HoI and the mod but using the moddir feature this time.
