So, something strange happened.
No change to my vimrc, I just did an update to the last version (you pushed some changes last night and today) and now the conceal is working again. Even the criticmarkup stuff.
I still have a suggestion: in substitution highlight can you eliminate the opening and closing tags? {~~ and ~~} and leavinge only something like soh~>so.
You can see in the picture below how it looks now.
