Doing a grep, I came across 34 of them. It took an entire day to rewrite the language string configuration substitutions in to the script files. Apparently, adding {$config[]} strings directly within the language files has been a thing since before I came on board with the coding in 2014. Though, prior to 2010, Ian and Rick really did a good job of keeping those things under control.
Fixed for UBB.threads 7.7.4
