[Bug] Null Sector. Composition. Testing ground: Ashlands

Got an issue in this mission. I've got a couple of emitters and headed to those locations.
Alpha location works perfect. I reached the location, installed the emitter, waited an hour, and fought off the animals.
Beta location. Installed the next emitter, killed a worm. That worm destroyed the emitter. And I really don't remember if this step was checked for me. After logging out it asks me to install another emitter, but when I install it - nothing happens. No worm spawn, no step check.
Chi location. Installed the emitter, timer reached 900 seconds and asks me to get there to check the emitter. After logging out and reaching that location the substep of reaching location checks but nothing happens. I can't interact with emitter, timer doesn't start, and after destroing it nothing happens either. And I can't place another emitter, because there is no that helper hologram.
