Maps Disconnect & Cannot leave Boss Arenas

This is actually 2 bugs that I've come across more than once:

1) Random points on the endgame map disconnect me to the log-in screen with no rhyme or reason.

- Random spots on the map whenever I go to traverse to it, regardless of the Waystone, has been probably say 10-15% of the time chance to just disconnect me from the game. It does not kick me out of the game entirely; just to the log in screen. There are probably a dozen points I cannot go in, and it's perfectly put to where I can't access the north part of the map because of these places being inaccessible. I've bricked MANY Waystones this way, and coming by tier 15's isn't easy.

2) Cannot leave boss arenas after I kill the boss.

- I've had this happen twice (and is also a reason for me writing this post), where I follow the edge of the map area and make my way to a boss, kill it, and then the "Arena" text that should be clickable, is basically not clickable/I'm unable to leave the arena and continue progressing on the map. Thankfully the bosses dropped tier 15 maps so I don't feel as bad because I can just use that same tier 15 again on another map, but the chances & hopes of getting other high-tier waystones when i have >200 monsters AND rares left on the map does feel really bad.

I'll further clarify that I am SOLO when this occurs still, as I do see this happening and a lot of other bug posts about it happening with being in a party/other players and having the same situation.
