Somehow the gun unit resource requirement wasn't nixed (MG and Bazooka still require oil too). It's easy to take out in the meantime.
They're also listed both as combat class melee and combat class recon.
Other "bug" notes: I think the added units (missile destroyer, bireme) would need their cost adjusted to the 2x scale, with an added 20% cost.
The unit upgrade cost is set at 1.5x instead of 2x.
Infantry still has a unit AI reference to paradrops from several versions ago.
Both Airborne and XCOM are listed as vanguard style units still. Intended?
There's an upgrade path for ships still in the start file alongside the upgrades file (redundant/overriding).
I don't see a change for walls to be 25% from 0. That list, part of it at least, is still in both the start and end sql files too (redundant/overriding).
Bazooka doesn't get a ranged defence bonus ala gatling gun and machine gun.
Aqueducts were nerfed to 30% from 40%, not documented?
I don't actually see the change to hand-axe (will check the interface/tools directories). - found it.
Carriers are still listed in that upgrades file to upgrade to missile destroyers and from destroyers (intended?, seems like a bad idea)
