Vehicle Replacement Bug

[Squab]

Last night, I played on one of the public servers.  The log flume that I built and several other coasters had their trains/cars/logs replaced with steam engines.  Guests were not in the steam engines.  It was rather hilarious to see a train floating down a log flume but still a glitch to be noted.  Cheers.

I don't think this is a bug. It's probably someone else on the server who replaced them with other vehicles. In the options menu you can check an option that then allows you to select vehicles from other track types for rides.
