Saint Louis is generally far below 25% Loyalty. The one town in Missouri that is usually over 25% -- I can't remember the name at the moment, but its at the end of the train line going west from Quincy IL through Bloomfield MO above the Missouri River -- but that doesn't have a harbor. Jefferson and Lexington MO usually have less the 25% loyalty too. Check all the Missouri harbors; if non of them are in a region with 25% or more loyalty, this will prevent you from building any riverine vessels in Missouri at all -- and this without a message.
Edit: just remembered the town's name, it's St. Joseph.
Ah those francs-tireurs of the Missouri stripe... bars I should say: they are busy even when nothing seems to be happening.
That town is St. Joseph MO, and no harbour. There's one just across the river though, in Ft. Leavenworth KS.
Edit: Just caught your edit.
