i think the bug about losing threads randomly and being ported to the archive is known (there was only 1 run i had where it felt like there was something fishy with the threads as i only remember dying twice)

not sure on being stuck in combat in the archive itself though

something that might help if you need to reset the archive instance there is an hourglass which forces the instance to reset and gives you the prompt to exit the instance

this is useful too if you finish a run and want to go again, you hit the hourglass to reset it so you can start a new run

that also seems unusual, as you can usually use interactive items in combat as long as you havent been attacked recently (like the merchants and other npcs)

based on what ive been reading on these threads about lost threads, it seems that most of the people who have had that happen are running solo

ive probably done about 75-90% of my runs in a 2 person group and dont think ive had any issues with randomly losing threads

overall i agree though that is not a fun way to end a run

i agree, theres numerous bugs with the archive that can make the experience not fun

• if enemies spawn too far away they will disappear and you can lose a thread
• enemies in some of the arenas can spawn underground making them nearly impossible to kill unless you have scorching support
• randomly losing threads (such as your case)
• the bonus stages with transformations (watcher/goat) can be bugged and cause gear to stop working unless you unequip and requip the gear
• in a run with 2 players, 1 player can fail to port into the bonus stage

ive lost track how many runs ive done but surprisingly had few issues, the worse one is probably the enemy spawning underground because then you remain perma stuck in combat and the only way to leave the instance is if you are in group and leave group
