Truckload of salt time. I had heard a similar story about Hex needing a Mad House 2.0 replacement from an old flatmate who works at Merlin, in a finance department of Resort Theme Parks. I was keeping schtubm mostly due to discretion and not wanting bragging rights etc, but with it being independently raised I thought I'd pop my head up and say I've also heard similar things.
Allegedly Vekoma were called out to assess Hex for repair, after replacement parts were ordered last season, installed and then "broke" this season. As the repairs were done internally by Towers and not by Vekoma, they looked it over and couldn't/wouldn't carry out any further work. They did, however, point out that they had a new shiny upgraded model that Towers could purchase, if they so wished. This is what I've heard they've done.
Is he telling the truth? I'm sure he is are far as he's concerned, or he's at least relaying a story he believes to be true. I wouldn't normally post a story like this on its own volition, but the fact that somebody else had allegedly heard something similar, made me think that it might be ok to share it.
