This usually means you called setState() on an unmounted component. This is a no-op. Please check the code `\r\n\r\nMy best guess is that there is a memory leak somewhere and new connect holds a reference to unmounted component. Triple checked that it doesn't happen with `4.4.5`. \r\n\r\nIt doesn't happen right away, only after I switch back and forth between routes that re-render a lot of components. I don't have time to dig deeper and set up a test project, but I can create a branch in my public repo where it's happening to reproduce.

I'm going to take a different approach and start with @Restuta's project and just start ripping out all the unrelated code until I'm left with the minimum code that reproduces the error.
