Ok - so 5 months ago, in the off season, prior to a refurb, and your statement is "on nearly every single day" which implies that some days it WAS working. This suggests to me more like 'several' one offs, rather than an ongoing issue.
We've heard ex-ops such as Spotty discuss how some effects aren't working or not refilled from day to day, and they report this to their leads, but once the ride is opened, there is not a lot that can be done about it except remind Tech services to look at it before the next day.
Does that mean it's acceptable? No. But you discuss these issues like it's an epidemic of failed theming across the board whereas in your own words you make allowances that it wasn't every day, and you're talking about observations around half a year out of date.
Clearly, when others have visited more recently, and not observed the same issues, this is a perfect example of #yourargumentisinvalid.
I shall have to review them when I get home and check it out.
