Help with random freezes?

[Sanzennin]

Just thought I'd ask. I usually get 1 to 2 random freezes that last for about 1 second per round. I don't think it has anything to do with graphics, as they can happen even when there is hardly anything happening on the screen, and the game doesn't lag at all when I got max amount of mobs taking all sorts of damage from max amount of defenses and heroes on the screen.
Also, my CPU doesn't spike and the RAM has plenty of headroom... So I'm kinda puzzled as to what could cause it?
It happens when I'm playing alone, and it happens when I'm in multiplayer not host (?).

It seems mostly random, but in little-horn valley it often happens when the barrel trap is activated. It also often happens early on every wave, after most mobs have spawned and walked some 25% of the way, but before defenses start firing. Sometimes it happens when the mobs have all already spawned and reached the defenses and are actively fighting. Sometimes it happens just a bit before the round ends. I don't think it has ever happened in building phase or in tavern.

It also seems to increase in frequency the longer I am playing. Sometimes it doesn't happen at all for several games.

I'm also getting the same thing and my laptop isn't a low-end kind either. My guess is that the game isn't optimised properly at the moment.
