Bugged in a Lootrun

I am currently bugged in a loot run. After completing the first challenge, it suddenly showed 12/12 completed challenges and that I should be warped back. Unfortunately, nothing happened, and I can no longer interact with the loot run master. I’ve tried various things like /class, restarting Minecraft, or leaving the area. None of it worked. I cant leave the lootrun and the timer doesnt work. What should I try to fix this problem?

 

I reckon you're doing lootrun during the buggy patch update.
At those time theres alot of bug going on, even players warned to not do lootruns with shouts (if you read it, you know it)

Other things that bugged at that time are:
1. Powder Visual bugs, even tho its visual, you cant use the Powder Special and get elem. damage from applied powder. If you applying powder to an equipment it will not show you applied those, but its fixed now.
2. You cant break flower pots. Yea. Somehow.

But it should be fine now
