Disabling reverse DNS breaks expression bindings on Vision project retarget

image
I turned this off recently because I was experiencing some latency when reading and writing to tags. It fixed the issue and I though my problems were done. Then I noticed that whenever I would navigate to a different project via system.util.retarget() or system.vision.retarget() any tag bindings would lose connection and same with database connections too. If I launch the desired project directly from the vision client launcher everything behaves as expected. Is there a cache or something I need to clear so I can retarget normally again? I only notice this in vision clients.
We only have one gateway also.
I'm running 8.3.4

I filed a ticket with support. They've identified it as bug likely with
retarget(). Tag connections weren't actually affected unless they were done via expressions. All expression bindings would fail after retargets. Just FYI.
