Proposal component crashes only in English for Roadmap process at meta.decidim

I clicked to create a new proposal, discovered that categories were not well translated, went to admin panel, translated categories, tried to create a new proposal, server crashed. I exit previously opened proposal, created a new one, server crashed. Now, when trying to access https://meta.decidim.barcelona/processes/roadmap/f/122/?locale=en the server crashes :-/
