It looks like the one compass issue (with it looking all messed up) is sporadic. On test today, I didn't have any problems with my compass or quest arrows. Rackat and I didn't have the problem but Capt Greengene did. The quest Ray of Light star when sailing is slightly off. I mean, it doesn't appear "dead on" the target ship but slightly behind it. It makes the compass seem like it's showing an extra ship in the vicinity.
Regarding the compass issue you have at the top of the OP, yeah, I noticed that. Did send a report about that displeasure. Checkin g your crew member positions isn't impossible though. You can still zoom in while at the helm, pan the deck, and look for the crew icons. Sure at a glance, you can't see. Personally I think the outer most zoom where you can see all visible ships in your sight range is a bit much. If I'm concerned about stuff that's happening that far out, I'll look with my eyes. Also, the inner most zoom isn't even the old default zoom. I used to be able to hit ships (with broadsides) just inside the compass circle, now I have to wait until they get within half of the compass radius. I really don't see what the problem with the old compass zoom settings was.
I didn't seem to having a problem with broadsides on my regular sloop.
The "You're already there!" teleport issue will probably be annoying to most people but since they did make the modification, I'm sure D wants it to be that way. I sent feedback about that but doubt they'll do anything about it.
Memory-wise, at this moment after an hour of play, my pirates.exe is only using 710MB of memory for me. I'm on my laptop right now (2GB dual core [affinity set only on CPU0], 2GB memory, integrated Intel video using shared memory). My desktop is having issues so I can't play on it until I get a new case and power supply.
Did notice that they moved Devil's Anvil to the east a bit. You can actually make a straight shot from PR to Tortuga without trying. I like it. I actually kind of miss Cuba being farther away from PR than it is now. It seems
too close.
[edit: LOL. Just launched from Tortuga, my compass was kind of whacked. It fixed itself after porting and relaunching]
