In no particular order:
1: The rifle grenades description appears to be wrong or the damage is too high. Currently it states something like "Weaker than a normal grenade but longer range", that's clearly not the case as in most cases it can wipe full health squads.
2: Pathing, has been made much worse for several if not all vehicles. For instance, the UC for the Brits that has to be facing the unit to fire, will, reverse to the destination no matter how far away it is or if you attack move or not.
3: British announcer will shout "We have lost a forward position" when a trench is destroyed, leading to confusion as the same is said when FRP or other sim city buildings are destroyed. He can also call out that the base is under attack when infact it is an emplacement.
4: British announcer will sometimes not call out when a structure has been destroyed, seen here:

5: British sniper will sometimes refuse to fire, almost like the is stuck in limbo where he needs to reload but is trying to shoot, to fix this you have to move the sniper then tell it to attack, at which point he will reload and then fire. In some cases he will take considerably longer to shoot than normal when nothing appears to be 'wrong' an example here:
https://youtu.be/Cn82_E2PB7E?t=34m51s (also happens against infantry when hold fire isn't on, nor the ability is used).
6: British sniper can fire the crit shot after you have selected it and then moved (which should cancel?) shown here:
https://youtu.be/Cn82_E2PB7E?t=37m53s
7: building out in the field, emplacements/sandbags etc will sometimes only cause 1 member to go to the destination whilst the rest stay put, as a result it wont be built and the squad will remain stationary.
(Unsure what causes this but it seems to be something to do with the distance that the player issues the squad to build (The greater the more chance it happens)))
8: Tommie's will shout "grenade!" before any animation has even taken place of the enemy throwing the grenade, mostly happens when the rifle grenade is about to be fired at them.
9: The Vickers (unsure if its the same for other MG's) will randomly decide to setup upon exiting a building leaving the squad vulnerable to wipes.
10: The vickers crew positioning is all wrong, they will stand infront of the gun, far away from the gun, wherever they feel like really causing it to be easily killed off.
11: Selecting a squad in a building by drawing a box over the house and then asking them to attack a specific enemy squad will only let you leave the building, to attack a specific squad you have to use the icons at the top right, left click on that and THEN left click on the squad.
12: Tulip rockets can and will hit a tank without causing any damage at all, basically going through the unit seen here:

)
13: Similar to above the same can happen with the AT gun:

14: Hold the line ability will sometimes refuse to send planes, on the other side the defence symbol can remain above infantry long after the ability has ended. I'm unsure if the buffs still apply. Both can be seen here:
https://youtu.be/Cn82_E2PB7E?t=1h4m50s watch until the ability ends, the IS still has the symbol.
For now, that's the ones that stand out to me, I hope this helps in someway.
