Every other build tab click sends you back to tab 0

Using Chrome 57.0.2987.110 on 64-bit linux, every other time I click a tab I get sent back to tab 0 instead of the tab I clicked.

The following shows up in the developer console:

[270.826s] [om.next] transacted '[(compassus.core/set-route! {:route :route/legacy-page}) {:compassus.core/route-data {:route/legacy-page [{:legacy/state [*]}], :route/projects [{:legacy/state [*]} {:app/current-user [{:user/organizations [:organization/name :organization/vcs-type :organization/avatar-url]} :user/login :user/bitbucket-authorized?]} {:app/route-data [{:route-data/organization [:organization/vcs-type :organization/name {:organization/projects [{:project/followers []} :project/vcs-url :project/name :project/parallelism :project/oss?]} {:organization/plan [*]} :organization/name]}]}], :route/account [{:legacy/state [*]} {:app/current-user [:user/login]} :app/subpage-route {:app/subpage-route-data {:integrations [{:app/current-user [{:user/identities [:identity/type :identity/login]}]}], :notifications [{:legacy/state [*]}], :heroku [{:legacy/state [*]}], :api [{:legacy/state [*]}], :plans [{:legacy/state [*]}], :beta [{:legacy/state [*]}], nil [{:app/current-user [{:user/identities [:identity/type :identity/login]}]}]}}]}}], #uuid "fdc8711e-7e6d-4b5c-bea5-509cf915ed95"

I also get some errors like this: pusher-94f425ff3b262f615972fa7cdfed368b.min.js:12 Pusher : Error : {"type":"WebSocketError","error":{"type":"PusherError","data":{"code":null,"message":"Existing subscription to [company github]"}}}
