Constant disconnect to log in losing Map Progress

So, three times in a row now ive plowed my way through the dam end map to reach citadels for these required fragments to actually REACH the Arbiter.

When i finially reach the Citidel Boss, half way through the fight i get booted to the log in screen, when i come back... Map failed, gg

This is the 3rd time in a row now, has also happened during a random Delirum map i blew an expansive map on i purchased, so bye bye that currency too.

I get its early access but to have no back up in place to re-attempt a map at the very least due to server issue is game breaking and very much detering me from continuing to play if i cant physically advance.

In addition to this. Same on Sekema Trials when already completed and in the reward room, only to be DC'ed and lose your rewards is just dumb. To be let back into reward rooms if you havnt selected the next trial room yet should be allowed, zero reason not too.
