Disabling reverse DNS breaks DB and OPC connections 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
