I've never heard of clones being damaged by high humidity. Unless they were sitting on the floor I can't imagine how they're pinning the blame on you. If this is a properly maintained grow room they were working in that room every day. How much water could have been on the floor if this occurred overnight? It sounds like much ado about nothing other than an opportunity for these people to sand bag you with all their garden problems that have nothing to do with water on the floor. High humidity doesn't cause a garden to be infected with bugs. Eggs hitchhike on clothing, shoes, and clones that are brought into the garden. All of which you are not the cause of nor is it your problem.
I'd ask the garden owner / manager a few questions that may help sort things out.
How do you feel water on the floor caused bugs to infest your garden?
How do you feel water on the floor damaged your clones that were elevated off the ground?
Plants in a vegetative state of growth prefer high humidity. How and why do you feel high humidity damaged your plants?
Did you inspect all of your clones prior to bringing them into your garden for pests?
Do you change your clothing and shoes prior to entering your garden?
Eventually stupid people get tired of more intelligent people asking them questions that expose their stupidity. At some point they just want it to stop. Fix the pipe and tell them to piss off.
