Just a friendly reminder, this host only runs the current stable and experimental branches (The two branches that The Fun Pimps officially support and acknowledge).

As such, regardless of your updgrade / update settings, your servers should be on the latest stable branch. If you experience issues on 19.4 or earlier, emails to the support staff will be replied to with a suggestion of upgrading to the supported version. 19.5 has been on experimental for quite some time now, so most modders worth their weight in salt should have a new version of their mod out shortly, if not already.
