Slitherine

First post - been playing the game for a while. Actually I've played thru the missions about 4 times already, focusing on different units and tactics. And learning as I go.
I'm honestly not sure how long its been going on for, but these issues feel like bugs to me and wondering if anyone else is as irritated by it as I am. I'm noticing now specifically after having bought the terminator DLC, but it may have been happening before.
- Zone of control. anyone and everything can move through my zone of control, and I simply don't hit them. I swing, but never connect. I'm talking about 98% - 99% failure rate. basically never. but if I move through the enemy ZoC, they hit 100% of the time.
- melee "fighting back". When I melee attack, if from the front, the enemy hits back. My troops do not. specifically noticing this on the terminators. fully facing the enemy, they get hit and just stand there. during my turn, I hit and get hit back. this doesn't seem normal to me.

Anyone else notice this / are irritated by this?

TIA (Cant wait for Necrons!!!!)

There is no back hitting when your unit is charged. Additionally the Hormagaunts have the skill to leap, which counts as charging, and then there will also be no hitting back.

If you want to charge with a unit without leap skill, don't do any movement. When a unit moves one point it won't be able to charge anymore. Just choose the melee attack of your unit and click on the enemy unit you want to charge. If there ist a direct path to the enemy unit, it will move and charge. It's described in tutorial #2.

But beware of pistol reaction fire.
