Sorry, but this sounds like folks who don't understand tech, and why we actually want/need our one opportunity to work out the kinks and solve the challenges. I have worked w directors who don't get it, who want to run and run and don't understand why we stop for technical glitches that arise, and it's frustrating. But remember, the actors and director had (n) weeks to solve their problems, reworking as they went. We have one or two days to put all the disparate pieces together (some of which we may be seeing for the first time), make sure no one gets hurt, the actors feel safe, the effects work, the costumes and props do what they're supposed to, the things that were overlooked or forgotten, the precision timing on scene shifts happens, etc. I for one don't feel it's fair for you to find out in front of an audience or get blamed for problems that they didn't allow you time and space to solve. Theater is experiential, and solving on paper or in theory is all well and good, but you gotta actually DO it to know.
You may not have a big set or costume plot, but you do say you have have acoustic issues, and sound cues and light cues that (I presume) require precision, meaning you have to try a couple of times to know exactly where to call them, what to look/listen for, etc. And if they insist on ignoring the tech, you can't take it personally if you don't get it perfectly the first, or even third, time. There's a reason we do it again once we get it right, to lock it in!
