Wow, you're an old timer wink

One thing that might work is if you have some sort of an idea of the largest POST_ID that has this problem. With that, you could do a mass update and set POST_BODY to be the same as POST_DEFAULT_BODY for all of those posts. So, say the problem stops at POST_ID 125367, you could run this query:

SQL Query
update ubbt_POSTS set POST_BODY = POST_DEFAULT_BODY where POST_ID > 125368
