A lot of enemies seem buggy of late.

1- First they made an update so that enemies would target structures more and for some reason completely ignoring you. Sometimes they would walk towards you, then back to the structure and back and forth again, doing absolutely nothing. Then they made another update.

2- Now they see you as a the primary target, however after this update had launched, enemies just won't target you at all sometimes. I have had deathsquito's hover in front of me wondering why they didn't attack me. Then i ran towards them, nothing, i jumped and attacked them. Just hovering there, no "scanning surroundings" icon above them. Just flying around a bit, doing nothing.
I've had all sorts of enemies literally walk into me, pushing me away. It's kinda stupid.
