Discord contacts can not be reached, after removing and adding them again

[TomTheDragon]

I am connected to my discord acc over the bridge and i had no problems to chat to everyone on my contact list so far, but i unfortunately removed one of the virtual contacts on the matrix side by accident I tried adding it again by entering his id (@discord_DISCORDUSERID:HOMESERVER) and he did show up in the search, but when i message him, nothing reaches on the discord side, but his name/icon seems to get updated I also tried to log out and in my discord acc on the bridge and to restart the bridge, but nothing seemed to fix the problem so far

I did some more testing and it seems that i can remove almost every Discord contact in my list, since if its gone, i will receive a invention for a new room again after a new message from that specific account got send. But i do have a hand full of contacts with which this is not working. I also tried using double-puppeting but did not fix my problem.

I also get errors like those in the console, when ever someone tries to send me something:
