Methods not calling if tab switched and sometimes randomly

I have an issue intermittently happening where the server is not being called by a method. If I switch away tabs and then click save on my module, everything is executing except the actual method call. This is happening to some of my users, and I’m unsure how to go about debugging it. No errors are shown and it’s happening on a page I haven’t touched in a while. It seems like the client is becoming disconnected from the server.

I’m on Meteor 1.6, but this issue just started happening today after a recent push. Here are the new packages I added in the push – could any of them be causing this?

+aldeed:autoform@5.8.0

Any thoughts/places to look?
