About the cloaking issue. There has been a little in house misunderstanding. The problem is that the way cloaking works now is that if you are being targetted but aren't locked you can cloak but the lock attempt isn't broken so when you're locked you get uncloaked but there is a bug where the uncloaking visual effect isn't performed so you happily think you're still cloaked.
The fix in the patch notes and the one Kieron mentioned fixes the issue of not seeing you uncloak. However cloaks didn't use to work this way, if nobody had you locked when you cloaked, all locking attempts were broken and you stayed happily cloaked. That is the way it supposed to work and we'll be restoring it back the way it was.
I don't really know when that will happen though. It was really news to me that this "wasn't a bug" until this morning so I've been talking to other devs and bughunters about this.
