Multiplayer Coop 5.2

[RaidR]

After downloading the 5.01 to 5.2 patch, I started a multiplayer coop game with a friend. 2 german players meeting engagement with 1 soviet player, location : kursk '43
4200/6200 bp

After a while playing I began to notice some really weird things, first of all, the soviet SMG squads were firing with an 120mm as main weapon (they even knocked out a tiger from 6 hexes distance), and a maxim hmg was firing 'molotov projectile' as primary weapon

does anyone else have these problems in multiplayer games with the ai? Or is this a 5.2 bug? I'm pretty sure we deleted our steel.prf files before updating
