issue with Archivist & Babel in a multicontext setup

[jonleverrier]

I'm using Archivist 1.2.4 / Xrouting 1.4.1 / Babel 3.0.0 in a multicontext setup with MODX 2.5.8.

When I click on a Archivist link such as /archive/2017/09/ and try and switch the language, babel reports the link to be /archive/?arc_year=2017&arc_month=09 even thought friendly URLs are switched on within MODX and Archivist.

The parameters in the url are causing a problem with my site caching (and generating 404's).

Could this be a problem with Archivist or Babel ? I'm not quite sure. Apologies if it's not a problem with Archivist.
