So far, in the years I've been playing ED, updates have broken/introduced:
- FSS
- ScanRam (twice)
- Death from Above (skimmers raining upon ships landing at planetary outposts)
- Mission payouts (haulage industry was screwed for months because of this)
- Removed Grade 5 materials (EFCs) for months.
- Introduced NPC Skynet ships with Terminator-style weapon load-outs (like multi-cannons firing PAs!)
- Remapped controller bindings without warning (at least on XB1), almost crashed my Cutter into a station wall thanks to that. Fun times.
- Broken BGS.
So, yeah, prepare for bugs, and not just the Thargoid kind.
