Some types of glitches that happen:
Missions not updating, you accept it, go to surface, then nothing, no map updates or messages, sometimes key things don't trigger (like dropping a mission item)
Freeze: A very large lag spike that either completely freezes ur surroundings or doesnt allow you to interact with them (shooting, collecting, etc)
Slow Response Devices: Devices work seconds after activated or never work at all, like an after burner starting late then ending late, or a blaster that takes energy but never fires, or collector starting late
Collector: You cannot collect certain items, as it is collecting and the little green bar is going down, it just resets and cooldown for no reason and you dont get the item. sometimes it can be fixed when you successfully collect another item, but sometimes certain items will be uncollectable by you
