@zweistein000 @Aliessil Well hotbuild works partially. The trick: Start a RCBM / Statera or any other servermod game that adds units / structures. You need to be in a running game ! Go to settings > hotbuild > the new units / structures should be in the list and addable. save and play game with full hotbuild. Tip: export those settings to a file using export system. The downside : If you start a vanilla and go into settings all the non vanilla units structures will be removed from hotbuild settings. Statera Rocket Defense example: So if you are clever you make export files per servermod you play. And when your servermod is started you just go import that servermod specific hotbuild file.
