Darkshine bonus broken causes unexpected disconnection on next zone

This is the merc lab we were running:



We grabbed the first 3 darkshrines (Room 1, Room 2, Room 7), which were impenetrable, acceleration, and replenishment respectively. After the third darkshrine in Room 7 we went to Room 10 to get the fourth.

When we did Izaro said "A potent little gift from our primitive past." and it removed our replenishment bonus without giving us a new one. It also did not list any bonus in the tab map listed under "Mysterious Harbingers Roam Wraeclast and Oriath".

This was odd for me knowing that they always provide beneficial bonuses but we rolled with it. I found the door to the third Aspirant's Trial first, clicked it to end the room, and received "An unexpected disconnection has occurred" and was logged out.

My friend on the other hand received the voice line "The pursuit of power can be a grotesque affair." (which is for Izaro dropping a unique item on death). Shortly after that my friend caught up to the room (after I was disconnected) and tried to enter the room as well. He received the message: "Error: failed to join instance because: disconnected from server." followed immediately by "Error: Failed to join any instances.". He tried a few more times to join the room receiving the same error message before running around for a bit. When he tried it again after a few minutes he received the same disconnection I did.

For both of us the game was running fine post fourth shrine and his continued to run fine after I disconnected, still receiving global and trade chat messages.

Yeah not too sure about this one and we're kind of sad about losing the lab progress :(.

After posting this I'm going to be running merc lab again to see if I can reproduce.

I ran through Merc lab again and did not receive the error. However this time I was solo and did not have my friend with me. It could be related to being in a party.
