[Mastery Test bug]

I was in Simaris's room practicing for my MR 20 test. After practicing twice I decided to qualify for the MR test i was doing. After choosing yes to qualify it i was waited a bit but it didn't start the test so I decided to choose qualify again. But instead of putting me in the test it said i need to wait 24 hours before i can do the test again. I didn't even fail or was put inside the test yet. pls do something about this.

[POE Drone is unhackable]

While I was doing a mission on POE it was fine until the drone escort mission. For some reason i cant hack it. Pressing space or the cipher didn't work so i had to abandon the mission. Please fix this.

[Plains Of Eidolon Hijack type bounty]

While I was doing bounties on POE everything was fine until i encountered 2 problems. First one is the drone doesn't spawn. When i was at the mission location the first thing i noticed is that the mission circle doesn't expand like it usually does. As i can't find the drone i decided to get out of the plains and do another bounty and the next one just so happen to be another hijack. And it was still the same small circle and drone doesn't spawn. The next problem is getting the drone to the objective. This problem really bothers me. As I was escorting the drone everything was fine and dandy except at the end of the objective. One of the grineer was either an arson or caustic eximus. As I was getting closer to the objective the eximus decided to release a fire blast and it hit the drone and blasted it away. I killed all the enemies at the end but i noticed i wasn't finished yet. I was looking around what went wrong and found out that the drone decided to not move to the objective. This only happens when i'm near the end of the escort.
