Hi, I've no idea what Topic talk:Sewfq489tp3iic43 is, either a weird name in the main name space, or a weird talk page for a namespace not needing any talk pages at all, but it's definitely unrelated to Topic:Sewfq489tp3iic43, please move it without leaving a redirect.
Topic on Project:Village Pump/Flow
Move to what place? You're the author of the talk page: Is it really needed, or maybe it can be deleted? How you created these talk page? :/
It's an experiment, I tried to figure out why an existing Topic:Sewfq489tp3iic43 contains a red link to itself, and is actually always shown as red link. Additional test:
| Namespace | Talkspace | ||
|---|---|---|---|
| 90 | Thread pages | 91 | Thread talk pages |
| 100 | Manual pages | 101 | Manual talk pages |
| 2600 | Topic pages | 2601 | pages |
Apparently there is no "Topic talk", the experiment ended up as article. JFTR this bogus article could be moved to Thread_talk:Project:Current_issues/Topic_talk:Sewfq489tp3iic43, as entertainment for the folks migrating Liquid threads to Flow, apparently namespace 91 is empty at the moment. But the red Topic:Sewfq489tp3iic43 is really wrong, it exists.
Done
Manual thanks, I miss the tnx-button whenever it doesn't show up—IPs, bots, liquid threads, … 
np :) Yeah, Flow would be better, just because you can thank another user for a post :D
