Thanks for the hard work, @IgorZ!! Much appreciated!
I think I need to report an annoying bug in my 1.11 install. I don't really know if it is better to report it here or in CKAN thread. CKAN marks the new version 1.8 as compatible for 1.11.0 to 1.99.99 so I updated it before reading in the OP that this is not true (minimun version 1.12). The observed behavior which made me report the issue is that in an already deployed vessel with a RTS-1, the option from the GUI to transfer just liquid fuel has disappeared. All the others are still there, including Oxigen, or LF+Ox, and so on. Reverting to 1.7 has proven to be the proper solution, but I guess CKAN info about compatible versions is not *ahem* really accurate (again). So, IgorZ, up to you, if you want me to report it to CKAN, no problem at all
Again, thank you!!
