Hey. Some of my guild members and I started clearing Operation: Mechagon on mythic difficulty last night, but seeing as it was getting late we decided to call it a night after having defeated the Aerial Oppression Unit. Today, we tried to log back in to finish clearing the dungeon; however, the dungeon has stopped us from being capable of progressing. When we enter the tunnel to enter the workshop, there is a misty wall there very similar to the ones found in mythic+ dungeons. It would appear to me, with my limited technical knowledge, that the game believes we cleared the first half on mythic+ when, in fact, we did not. I’m not really sure what to do about progressing in this case. We’ve tried leaving and resetting instances, changing the group leader, switching to heroic difficulty then back. Nothing’s working. I hope we can get this resolved before the weekly reset so we can finish clearing the dungeon, but any resolution would be very much appreciated. Thanks. 
i think they broke the dungeon into two parts. The first part and the second part no longer relvent i guess, u just talked to the npc and teleport you to the workshop entrance
that didnt explain anything theres still a wall cant do mythic 0 work shop. Ive tried everything cant do it with out a key ?
Having same issue still, whats wrong? Trying to run workshop and theres a wall there
FIGURED IT OUT! If you are running regular mythic, you have to clear junkyard first
Yea m0 doesn’t distinguish between junkyard and workshop. You have to do both.
That didn’t figure anything out. The original poster said they already cleared the first portion but the wall is there. I’m running into the exact same thing now. Killed first 4 bosses last night, went back in today before weekly reset, wall go into workshop and first 4 bosses still dead.
My group just had the same issue as the OP.
Almost a year later, this is still not fixed. I cleared Junkyard prior to servers going down for maintenance. My lockout shows me at 4/8, Junkyard is totally empty; entering the instance puts me in the Junkwatt Depot, rather than at the start. Everything seems to recognize that Junkyard is clear, and the yellow wall is up stopping me from getting into the Robodrome. Using the NPC to port in/out didn’t work, resetting instances didn’t work, extending my lockout didn’t work. I’m completely blocked from doing the second half of the dungeon this week, because of this 
Getting this issue as well, coming back after clearing 4/8 earlier in the week.
Guess I’ll chime in and say it just happened to me on 1/6/22. Guess the lesson here is that you have to clear it in one run.
You mean clear without logging off, what a joke.
Ran into this issue today. Why is this even a thing?
Ran into this morning when I logged in to finish 2nd half.
I guess this is low priority to fix.
Bump, still an issue, ran into it today after doing 4/8 yesterday.
… wish I had come across this forum before I did the same thing yesterday - and yes, it is still an issue. Note to Self: make plenty of time to do it all in one shot before attempting again.
I got this to work. I had to kill the tussle tonks and log out with my main after that. Then my alt would zone in before the trash leading to KUJO (right where you loot the chest for the bots).
I just got the quest to kill the king and I tried to enter the dungeon via the entrance but I got the load screen for a slip second and then I’m back at rust bolt is anyone else having this issue I mean I know I can skip the dungeon and I have but it really bugs me that I can’t even enter the dungeon I’ve seen the op and others with the op issues but I’m not seeing anyone with the issue I’m facing
Still an issue as of 3/1/24.
