Killed a topic in redis, category won't render

[Guiri]

Delete/purge didn't work on a topic. When I'd click into it, it would just hang. So I went into redis-cli like an idiot, found the hash, and deleted it:

hgetall "topic:1949"
 1) "tid"
 2) "1949"
 3) "uid"
 4) "1"
 5) "cid"
 6) "2"
 7) "mainPid"
 8) "0"
 9) "title"
10) "Billy The Kid Versus Dracula (1966)"
11) "slug"
12) "1949/billy-the-kid-versus-dracula-1966"
13) "timestamp"
14) "1432861863102"
15) "lastposttime"
16) "0"
17) "postcount"
18) "0"
19) "viewcount"
20) "0"
21) "locked"
22) "0"
23) "deleted"
24) "0"
25) "pinned"
26) "0"
127.0.0.1:6379> del "topic:1949"

Only now, the clicking into the category kills NodeBB.

The /home/user changed, actually, when I moved machines. I assume I'll have to manually fix this in Redis?

Is this recoverable, @julian?

[baris]

Is this on latest?

[Guiri]

Yes. 1b88a6a5239b16fc91a8559ad1e03d3bc92a7013

[Guiri]

Is there a way to rebuild the category or kill whatever reference to the topic I forgot to delete?

[baris]

I made a change on master so it doesn't crash. Can you give it another shot.

[Guiri]

Can you merge into 0.7.x?
