I have recently seen that your HashBuddy plugin has been automatically converting apostrophes to hashtag links in my blog posts and forum topics (and of course the buddypress activity stream) and it is a big issue.
I have had to deactivate this plugin (once I deactivated it all was fine) and use another one until that can be fixed. Amongst all you do could you please look into this and see if it is a simple error for you to fix and how long before an update with this fixed can be out?
I think this is a great plugin but I am not sure why this error is appearing.
I am using the latest version of this plugin, BuddyPress, WordPress, bbPress and a few other plugins.
