Guild Wars 2

Just came off Skyhammer map in PvP, and two bugs popped up (played Skyhammer quite a few times now so familiar with it)
1-: Unable to finish players if they are at a certain angle to columns. All you will get is ‘miss, miss, miss’. When the player revives, they can move through the column, to the other side (or at least, that is what I saw).
2-: Ranger vines disabling all skills if you get caught, when jumping down. When I say disabled, the vines are untargetable, and you can not activate any skills, including Plauge, which does not require a target to activate, even though the skill buttons are clear and have not been put into cool down by some other skill. So not sure if that is a problem with Vines, or the map itself, although it is the first time I have encountered it.
(Did not know whether to post here , or in PvP, so please feel free to move if I put it in the wrong place).
