1) Sniper Ace's artillery strike does not seem to work--even when he has Veterancy 1, the artillery strike button is still grayed out and it says "this ability is currently in use" and it never becomes available. The vet 2 attack works though.
2) Can't build more than one artillery firebase...maybe this is intentional, but when I try to build a second one, I get a message saying "requires artillery firebase" and it won't let me build it.
Other than that, pathfinding for infantry and tank units seems kind of buggy. When I set a waypoint for tanks they will often go forwards then suddenly go backwards then go forwards again, also often they'll pick horrible paths like turning around with their rear to enemy AT guns when I told it to go straight forward. Sometimes this sort of thing happens in the vanilla game but it seems worse in EF. This happens with all factions.
Infantry sometimes will get stuck on certain paths and keep going forward and backwards especially if there are a few units trying to go across a narrow area, for example the right bridge in the middle of the Semois map. This seems to only happen with Soviet units.
The pathfinding isn't gamebreaking but it can be annoying sometimes if my units are under attack.
Other than that, keep up the good work, 1.23 is definitely the best version of EF so far. I've totally abandoned the Vanilla game and am having a lot of fun playing against the AI with all factions.
