I remeber back in the day before the big ocean content when it was as basic as it got trying to hunt some of the bigger sea monster.  It was near impossible do to beuse for no reason what so ever standing right next to the sea monster he moved a milimeter and reset full HP and you had to start all over.  Today deicded to start doing daylie missions so I can uppgrade to a Carrack so go out and kill some Candidum sea monster.  And the shame damn problem I had 5-6 years ago still an issue the monster keeps reseting just moving like an inch  and bam full HP.  It took me about 50-60 canons balls to get him to not to go full reset sure he would still reset location and HP allot of times but at the end thanks to Mirciales of some GOD I manage to kill one.

So in 8 dang years the game has been out and this is an acppected feature of them game ??  Is Todd Howard gonna crawl out PA´s beheind and say It just works ?

Sounds like a skill issue, buddy.
