Boss arena locking you in or out

So I have had the issue many people have had where when you fight a boss in a map that has a boss "arena" area you can get locked in it and cannot defeat all of the rare monsters to complete the map. Knowing and having experienced this, I have been doing the bosses last in my maps so if I get locked into it I have already finished the map. Well, the opposite just happened, where I barely walked into a boss arena and backed out to finish the map, only to realize when I got back, I could not get into the arena. This really is annoying. I juiced this map with tablets and a good waystone, and I am aware that usually logging out without creating a portal can reset it if you are stuck inside. However, I was stuck outside of it, and unfortunately had created a portal to sell, so no way to get in. Please fix GGG, it sucks this map is ruined now, and I guess I should just remember which maps have bosses with arenas and just avoid them? This makes me not want to continue maps just because I also heard about the Citadels being bugged where you can full clear the map and it says there are still enemies left. I have found a citadel and have avoided trying it because I wanted to wait until this is fixed so I don't lose it to a bug. I already speed run T15 and am waiting to do Citadels, so what am I really doing in maps at this point. I don't really know what content is worth striving for and these bugs are making the end game seem pointless. Idk, what are people striving to do in this game after T15 is a walking simulator?

Yeah, in the last few days ive lost more waystones than i can rememebr! ive clocked in over 600 hours now according to Steam & can safely say im addicted to this game!

The BIG problem im having though, is despite the addiction the game is constantly F***G me over....no other way to say it :/

Ive lost a minimum of 2 Citadels in the last week to different bugs, had to repeat maps even AFTER 100% clearing (this one really gets to me..... i exit the game properly after clearing a map, only to find the "Map Attempted" status when i return to the game at a later date!).

Although it wouldnt be a bad idea for me to "move on" & play a different game.....these issues need fixing asap, as the vast majority of users are nowhere near as lenient as myself.
