Important : to players who can't save their templates, DISABLE ANY MOD, launch a game where you prepare all your templates, save them. Then reactivate your mods.
EDIT:
Here are versions of GAZUI and Hotbuild compatible with Nomads. They can be improved by adding icons for units that don't have one yet, but they work properly.
It is recommended to replace all previous version of GAZUI and Hotbuild by these so that there is no need to switch between the 2 versions when playing a Nomad game.
NB: it may require a second game start before the mods are effectively activated, but after that, you're good to go for as long as they are not deactivated.
