[12:13:36] <jfolv>	 Interesting issue here, ReplaceText seems to break all thumbnails on any page it edits. Purging the cache via action=purge fixes the problem, but it's strange that it happens at all. And it's consistent, too. I can replicate it every time. Don't even know where to begin debugging this one.
[12:23:25] <jfolv>	 It's only ReplaceText edits, by the way. Manual ones don't cause this problem.
[12:23:43] <jfolv>	 1.43.0 with the corresponding version of RT, as well.
