I mean, if the rumors of what happened last month are true, then they've managed to crash the Log Flume twice in the past 4 years (2 of those years it was closed for refurb so it hasn't exactly been open a lot of days to have crashed twice!) and the most recent one involved them having to pluck people out of the section over Bugs Bunny National Park just past the top of the lift hill with a cherry picker. Again, just a rumor so take it with a grain of salt. But it wouldn't just shut down for the hell of it so obviously something rather nefarious happened.
Also as far as the Round Up goes, it was old (like...45 years old) and has been moved several times within the park. It was one of the slowest round ups I've ever seen and barely raised off the ground. It should be easily replaceable by a new round up but that's probably too much to ask for.
Losing the flume would suck for sure. And I doubt they'd ever replace it. Sucks that flumes are going by the wayside.
